Amid continuing rumors that Apple is looking to increase the size of the iPhone display from the existing 3.5-inch screen to something in the range of 4 inches, one persistent concern has been how Apple would deal with the change in screen dimensions.

All models of the iPhone and iPod touch released to date have carried a 3.5-inch screen with a 3:2 aspect ratio, allowing developers to target their apps at a single screen size. With the addition of Retina displays in 2010, the screens now come at much higher resolution, but the extra resolution is dedicated to increasing the visual quality of content rather than increasing screen real estate. The introduction of the iPad in 2010 added a new display size to the mix, but the considerable difference in screen size compared to the iPhone made it reasonable for developers to create custom interfaces, either in the form of universal apps or separate iPad and iPhone apps, for use on the different devices.

But moving to a slightly-larger iPhone display would seem to cause issues for Apple and its developers, with the company seemingly having two options: either increasing pixel size to keep the same resolution but on a slightly larger display; or maintaining pixel size and increasing resolution correspondingly. The former solution would allow existing iPhone apps to fit the new device's screen with no modifications but with only limited utility, while the latter solution would seem to require developers target yet another screen size with their apps.

But as outlined at The Verge, one method for achieving the latter solution in moving to a 4-inch display would be to change the aspect ratio, maintaining the existing 640 pixel width but stretching the height of the display until it reaches a 4-inch diagonal. Simple geometry yields a screen height of roughly 1152 pixels for a 4-inch display, compared to 960 pixels on the current 3.5-inch display.

The forum poster, a user by the name of modilwar, was inspired by a comment from a caller named "Colin" on The Vergecast show who suggested that change in aspect ratio as a possibility for a larger display. Using that idea, modilwar developed a series of illustrations showing how this could be achieved.

At the most basic level, an increase in the height of the display would allow Apple to show five rows of icons on each page of the iPhone's home screen, up from the current four rows. Apple would also likely find it fairly easy to augment its own apps to take full advantage of the increased vertical screen real estate.

As for third-party apps, modilwar notes that many apps already utilize standard interface elements such as navigation buttons and bars at the top and bottom of the screen supporting a larger main content window in the middle. In the case of these apps, the main windows could simply expand vertically to show more content than on the current iPhone. Examples include browsers that could show more of a webpage, Twitter apps that could show more of a timeline, and mapping apps that could show more map tiles.

Other apps with custom user interface elements would require a bit more work, but in the meantime could simply be displayed at their current sizes with a 96-pixel wide black bar at top and bottom on the larger 4-inch display.

This new 4-inch screen with a 9:5 aspect ratio would also perform much better at displaying widescreen 16:9 video content, leaving bars on either side of the screen that are only 7 pixels wide, compared to 50 pixels for unzoomed content on the current iPhone.

Modilwar passes off his post as an intellectual exercise simple showing one way in which Apple could make a change to the iPhone's display with a minimum of disruption to the iOS ecosystem, but in a bit of a curious turn the post was picked up by Daring Fireball's John Gruber, who hints that the original idea may not be all that far-fetched.

Methinks “Colin” wasn’t merely guessing or idly speculating.

Since Gruber has been known to speak coyly about his occasional inside knowledge, it is unclear whether he has independent knowledge supporting the idea of a taller display for the iPhone or if he simply has a gut feeling that "Colin" may legitimately be tipping some information at least partially tied to Apple's thinking.

Update: "Colin" has been revealed to be Timothy Collins, who has no direct association with Apple.

As noted by AppleInsider, third-party resellers are beginning to experience shortages of Apple's 15-inch MacBook Pro, hinting that a refresh may be coming in the near future.

Among those resellers reflecting backorder status on some of the current 15-inch MacBook Pros is J&R, which is now sold out of both the 2.2GHz model, which is listed as "out of stock," and the 2.4GHz variety, which is currently advertised as "on order."

In addition, Best Buy has also stopped accepting online orders for the 2.4GHz model for home delivery. The 15-inch notebook is still available on a store-by-store basis, however a quick check of individual store inventory in cities such as Chicago and Austin similarly indicate that between 40 and 60 percent of those shops are similarly reflecting stock outs.

Apple's own online store is not yet showing any delays in fulfilling orders, but the company prioritizes its own distribution channels over third-party resellers, meaning that shortages generally show up first at those resellers.

Apple has been said to be ramping up production of new 15-inch MacBook Pro models carrying a thinner form factor, with Intel's rumored April 29 debut of quad-core mobile Ivy Bridge processors undoubtedly driving that timeline.

With dual-core Ivy Bridge processors not launching until early June, it seems that Apple may not be launching upgraded 13-inch MacBook Pro models until that time. As for the 17-inch MacBook Pro, AppleInsider had previously claimed that Apple was likely to use a staggered rollout of the new MacBook Pro form factor, with the 17-inch model not receiving an update until perhaps several months after the smaller models.

AllThingsD today announced that Apple CEO Tim Cook will be the opening keynote speaker at the D10 Conference scheduled for late May. Cook will appear in an evening interview session on Tuesday, May 29 in Rancho Palos Verdes, California.

Walt Mossberg and I could not be more thrilled to announce that Tim Cook, CEO of Apple, will be the opening-night speaker at our 10th D: All Things Digital conference.

It will be Cook’s first appearance at D, as well as his first time being onstage at an event not run by Apple or for investors since he was named CEO last August.

Steve Jobs made a number of appearances at the D conferences, including a notable joint appearance with Bill Gates at D5 in 2007 and his final appearance there at D8 in 2010.

The Flashback malware affecting OS X systems has gained quite a bit of publicity since it was disclosed last week that over 600,000 Macs have been infected by the malware. Flashback began life last year as a trojan and has morphed into a drive-by download taking advantage of a vulnerability in Java that Apple did not patch until last week, despite Oracle having released patches for other systems back in February.

Over the past few days, a few additional tidbits of information on Flashback have surfaced, including the arrival of some new tools to help users manage the threat.

- As noted by Ars Technica, a new Mac app by the name of Flashback Checker has been released to help users determine whether their machines have been infected. Users have been instructed to use Terminal to enter commands searching for files created by the malware upon infection, and Flashback Checker offers a simple packaging of these commands behind a user interface. While the app is incredibly simple and does not offer assistance with removing Flashback if it is found on a given system, it does provide a more familiar interface for those who might be intimidated by delving into Terminal on their own.

- OpenDNS has announced that it has included filtering of Flashback in its services. OpenDNS offers a number of features to improve resolution of domain names, and the new filtering of Flashback helps prevent infection while also preventing already-infected machines from communicating with the command-and-control servers being used to deliver instructions to the infected machines.

- Forbes has an interview with Boris Sharov of Russian security firm Dr. Web, which was first to bring the magnitude of the Flashback threat to light. In the interview, Sharov describes how difficult it was to even track down the proper team at Apple with which to share their data, also noting how uncommunicative Apple has been throughout the process. In fact, the only sign of interest they've seen from Apple is the company's efforts to shut down the "sinkhole" Dr. Web was using to reroute traffic from infected machines to gauge how widespread the infections are.

“They told the registrar this [domain] is involved in a malicious scheme. Which would be true if we weren’t the ones controlling it and not doing any harm to users,” says Sharov. “This seems to mean that Apple is not considering our work as a help. It’s just annoying them.”

Sharov believes that Apple’s attempt to shut down its monitoring server was an honest mistake. But it’s a symptom of the company’s typically tight-lipped attitude. In fact, Sharov says that since Dr. Web first contacted Apple to share its findings about the unprecedented Mac-based botnet, it hasn’t received a response. “We’ve given them all the data we have,” he says. “We’ve heard nothing from them until this.”

Security experts at Kaspersky Lab, which verified Dr. Web's assessment of Flashback's prevalence, indicate that Apple is indeed taking the proper steps to address the threat, including tracking and shutting down the servers being used by the malware. But the company has little experience with threats of this magnitude and is undoubtedly scrambling to keep on top of the situation.

Apple's stock has continued its remarkable run in 2012, moving up another 1% today to briefly hit a market capitalization of $600 billion. The milestone comes just under six weeks after hitting $500 billion, and Apple's stock is now up nearly 60% since the beginning of the year.

If some analysts are to be believed, the $600 billion mark is just a brief stop on the company's way to a trillion dollar market capitalization. Analysts are beginning to float that unprecedented number as a target for Apple's stock price over the next year or so.

Apple is now within just a few billion dollars of taking Microsoft's title of most valuable publicly-traded company ever, targeting its rivals' $604 billion market capitalization achieved in December 1999. But adjusting for inflation, Microsoft's market capitalization at that time would correspond to over $800 billion in today's dollars.

The Wall Street Journal reports that the four major U.S. wireless carriers have reached an agreement with the Federal Communications Commission to work toward a centralized database to track and disable stolen mobile phones.

The database, which the wireless companies will build and maintain, will be designed to track phones that are reported as lost or stolen and deny them voice and data service. The idea is to reduce crime by making it difficult or impossible to actually use a stolen device, reducing resale value.

Currently, Verizon Communications Inc. and Sprint Nextel Corp. block phones that are reported stolen from being reactivated. AT&T Inc. and Deutsche Telekom AG's T-Mobile USA don't. All four have agreed to be part of the new database.

The report cites a study from the New York Police Department showing that electronics are now the most commonly stolen type of property, with mobile phones accounting for over 80% of thefts in that category.

According to the plan, the major carriers will develop individual databases within six months, integrating them over the following 12 months. Smaller carriers will also join the database after that point. The database will also be interoperable with similar efforts in other countries to allow for international tracking of stolen phones, although many countries have yet to develop such databases.

As noted by ifoAppleStore, Apple has typically taken a hands-off approach when it comes to stolen phones, with Genius Bar staff routinely offering free warranty replacements in exchange for stolen phones. Apple's policies reportedly stem from a lack of centralized tracking of stolen devices and a desire to not become involved in potential confrontations over the stolen merchandise, but an official database supported by the carriers could help Apple become more proactive about handling stolen iPhones.

This weekend, AT&T began unlocking iPhones for off-contract customers. This allows the iPhone be used with a SIM-card from overseas carriers, or T-Mobile in the U.S. In addition to unlocking phones for off-contract customers, AT&T is also quietly unlocking iPhones for U.S. service members still under contract with the carrier.

Carriers are required by federal law to suspend service without penalty for deployed military personnel upon presentation of their military orders, but AT&T is not required to unlock the phones of deployed service members. Instead, the company is choosing to do that on its own.

AT&T declined to comment, but we have independently confirmed that AT&T is unlocking phones for service members upon request. Deployed soldiers, airmen, sailors, and Marines should contact AT&T customer service to get more information about having their iPhones unlocked.

Facebook has announced it is buying the extremely popular photography app-maker Instagram for a reported $1 billion.

Facebook founder and CEO Mark Zuckerberg announced the acquisition in a blog post today:

For years, we've focused on building the best experience for sharing photos with your friends and family. Now, we'll be able to work even more closely with the Instagram team to also offer the best experiences for sharing beautiful mobile photos with people based on your interests.

We believe these are different experiences that complement each other. But in order to do this well, we need to be mindful about keeping and building on Instagram's strengths and features rather than just trying to integrate everything into Facebook.

That's why we're committed to building and growing Instagram independently. Millions of people around the world love the Instagram app and the brand associated with it, and our goal is to help spread this app and brand to even more people.

Apple named Instagram its iPhone App of the Year for 2011. Instagram is also the 19th most downloaded free iPhone app of all-time. Instagram launched an Android app just last week.

Topeka Capital Markets analyst Brian White has released a new research report today outlining some of the takeaways from a recent trip to Asia to talk with companies in Apple's supply chain. According to White, chatter from those suppliers is pointing toward a larger 4-inch screen on the iPhone 5, which will also include a redesign bringing a "new, sleek look".

In our view, this will be the most significant iPhone upgrade with a four-inch screen and a new, sleek look that we believe will require a Unibody case. This new, sleek look will be the most important reason that consumers decide to upgrade to the iPhone 5, while we believe the addition of 4G will also attract buyers of the new device.

White notes that some suppliers are expected to begin ramping production of components in June, ahead of a launch in the August-September timeframe leading into a blockbuster final quarter of 2012.

As in any discussion of a larger screen on an iPhone, the issue of screen resolution is certain to be a key sticking point. With the iPhone currently offering a 3.5-inch Retina display, an increase to 4 inches would require one of two changes: an increase in resolution that would yield difficulties for developers by adding yet another device size to the mix, or a decrease in pixel density that would maintain the current resolution but see density drop to roughly 285 pixels per inch from the current 326 pixels per inch.

Among White's other takeaways from his trip:

- Display issues have caused a bit of a bottleneck on supplies of the new iPad, but the shortages seem to be easing. Any small constraints on March quarter sales numbers would be compensated for by a boost to June quarter sales.

- Suppliers suggest that a smaller "iPad mini" is still in the works, but launch timing remains unknown.

- While the new iPad is not yet officially available in China, some resellers are already carrying the device. Speculation is pointing to a potential May release for the new iPad in China, although evidence for that timeframe beyond a recent regulatory approval appears scant.

9to5Mac claims that Apple is internally testing new iPhone hardware that is based on a variant of the A5X system-on-a-chip used in the new iPad, with the company disguising the hardware in existing iPhone 4/4S bodies in order to keep its potential plans for a new form factor a secret.

Much like they did last year, Apple has internally seeded a prototype next-generation iPhone with the iPhone 4 design. The actual next-generation iPhone is specifically said to not include the iPhone 4/4S design, but Apple is testing these new devices in older casings to throw off leaks. The purpose of the prototype iPhone that we heard about is to test a variation of the “A5X” chip in an iPhone.

With the A5X having been designed with quad-core graphics in order to drive the Retina display of the new iPad, the variant being used in the iPhone prototype will emphasize other performance gains coming from the S5L8945X application processor included in the package. Like the new iPad, the prototype iPhone 5 reportedly includes 1 GB of RAM, up from the 512 MB found in the iPhone 4S. According to the report, the test iPhone 5 hardware carries a code name of N96.

The report also cites evidence of an "iPod5,1" reference in iOS 5.1 code suggesting that Apple is working on a hardware update for the iPod touch. The device was left nearly untouched in last October's update, with the addition of white models being the primary physical change to the lineup as the iPod touch retained the A4 chip even as the iPhone 4S received an upgrade to the A5.

Proving that Foxconn employees, even those associated with worker hiring, aren't necessarily privy to information on launch schedules for Apple products, Kotaku reports on an article from Maeil Business Newspaper offering new claims on an iPhone 5 launch date. The report notes that the newspaper contacted the chief of human resources at Foxconn's facility in Taiyuan, China to ask about hiring and iPhone plans, with the employee disclosing that the company has just received an order from Apple for the iPhone 5 ahead of an expected launch date of "around October".

According to a recently published article, the paper asked the head of human resources at Foxconn's Taiyuan factory about the iPhone 5 release date. The human resources head apparently told the paper, "We just got the order. It [the release] will be around October."

The report comes just after a Foxconn recruiter at the same plant claimed last week that a hiring surge of roughly 18,000 workers is supporting production of the iPhone 5 for a June launch.

As we noted in our earlier report, a September-October timeframe has seemed much more likely than a return to a mid-year launch, as Apple would likely prefer to maintain at least a one-year interval between product updates. Returning to a June-July launch for the next-generation iPhone would bring that interval down to only 8-9 months, a rather fast turnaround for the company that is still rolling out the iPhone 4S to new markets and carriers.

On Friday, AT&T released a statement that they would now be offering SIM unlocks for iPhones that are no longer under contract. The process of SIM unlocking a phone allows it to use SIM cards from other carriers. This feature is frequently used during international travel to allow the use of mobile service from local carriers. The Next Web detailed the basic steps required by AT&T.

The process is painless and only takes a few minutes in the chat. The only piece of information required by AT&T is the International Mobile Equipment Identity (IMEI) number, which can be found under Settings>General>About on your device.

Once you’ve completed the procedure, Apple pushes the unlock code during the next 72 hours to your email address, so the code comes from the mothership, not from AT&T. Once Apple completes the unlock request, a customer has to back-up and restore and tether the device to iTunes to complete the unlock process.

MacRumors readers shared their experiences on Sunday trying to unlock their out-of-contract iPhones in our discussion thread on the topic. Responses from AT&T service representatives were mixed with some seemingly unaware of the process.

Others had better luck, such as Exegesis48, who was able to get his iPhone 3GS unlocked immediately.

I called AT&T Tech Support and was able to get my iPhone 3GS unlocked no problem. In fact, the representative waited on the line to ensure I received my unlock confirmation email, at which point he told me to backup and restore my phone to receive my unlock. I did this and was able to receive my unlock IMMEDIATELY.

Experiences may have improved over the day. Some early callers were told the process would complete on April 16th, while others were told to simply wait 48-72 hours for the confirmation email.

Several readers have noticed that Universal Studios' movies are now available for re-download through Apple's iCloud service. In March we reported that both Fox and Universal were not yet participating in iCloud video streaming due to contractual obligations with HBO. HBO was reportedly working with both Fox and Universal to loosen these restrictions.

HBO agreed to loosen its arrangement with Warner Bros., which is working with iCloud, and also is in talks with Universal and Fox to do the same, the spokesman added.

When searching for movies in iTunes, Universal movies no longer contain a warning that the movies are not available through iCloud, while Fox's movies retain the warning:

Another reader was able to confirm he was able to re-download 40 Year Old Virgin. Previous movie purchases from Universal should now be available for redownload in your previous purchased menu on iTunes.

Fox is also said to be in negotiations with expectations that their movies would also become available through iCloud in the near future.

Digitimes points to a report in Taiwan's Economic Daily News claiming that Apple is planning to introduce updated iMac models in June, a bit later than some had initially hoped given Intel's Ivy Bridge launch schedule that would see quad-core desktop processors launch at the end of this month.

PC ODM Quanta Computer and chassis supplier Foxconn Technology are expected to benefit from the launch of Apple's latest iMac desktops, which are set to launch in June with Intel's latest Ivy Bridge processors, according to a Chinese-language Economic Daily News (EDN) report citing sources from the upstream supply chain.

The report repeats a claim from earlier this week indicating that Apple will be using anti-reflective glass for the new iMac, and also suggests that updated MacBook Pro models are due "at the end of the second quarter".

Unfortunately, Economic Daily News does not have a terribly good track record when it comes to Apple rumors, with past misses including an iPhone nano in 2009, a 7-inch iPad in 2010, and a Retina-display iPad by the end of 2011. But perhaps coming in support of the newspaper's claim of a June launch for updated iMac models, How to Arena earlier this week claimed a similar June-July timeframe for updated iMac models.

As for Economic Daily News' claim that Apple will be releasing MacBook Pro updates at the end of the quarter, which would mean late June, Apple's situation appears to be complicated by chip availability from Intel. While quad-core chips appropriate for the 15-inch and 17-inch MacBook Pro are said to be launching on April 29, dual-core chips viewed as successors to those used in the current 13-inch model do not appear to be launching until early June.

Recent reports have indicated that production on new 15-inch models has begun ramping up but that 13-inch MacBook Pro updates won't begin ramping until June, and it is unclear whether Apple would introduce the new 15-inch models before the 13-inch models are ready.

AppleGazette has assembled a large collection of photographs taken inside Apple Headquarters in Cupertino. The collection includes photos of the reception areas at 1 Infinite Loop, shots of the atriums, The Company Store, Apple's Town Hall auditorium, the Apple gymnasium and more.

For such a private and secretive company, there are a decent number of photos taken inside the walls of headquarters. Of course, we have seen lots of plans for the new Apple headquarters which should be completed in a few years.

Reuters reports that five people have been charged with intentional injury in southern China after a teenager sold one of his kidneys in order to purchase an iPad and iPhone. According to the report, those charged include the surgeon who removed the kidney and another person who arranged for the transplant into an undisclosed recipient.

The boy, identified only by his surname Wang, now suffers from renal deficiency, Xinhua quoted prosecutors in Chenzhou city, Hunan province as saying.

According to the Xinhua account, one of the defendants received about 220,000 yuan (about $35,000) to arrange the transplant. He paid Wang 22,000 yuan and split the rest with the surgeon, the three other defendants and other medical staff.

The iPad 2 in Apple's Chinese online store ranges from 2,988-5,499 yuan, while iPhone pricing begins at 2,888 yuan for an unlocked iPhone 3GS and goes up to 6,788 yuan for a 64 GB iPhone 4S.

The report indicates that Wang is from Anhui, one of the poorest provinces in China, and that he is suffering from renal deficiency since the transplant, a condition that is continuing to worsen. Interestingly, a nearly identical story surfaced last June, and while the teenager in that case was identified by a surname of "Zheng", the cases are so similar in their details that they may be referring to the same event.

Trading and sale of human organs is banned in China, where low organ donation rates have led those in need of transplants to seek out alternatives to established organ matching programs.

AT&T has announced it will begin unlocking customers' iPhones once their 2-year contracts have expired. The move will free up the currently-locked devices to use a micro-SIM from any carrier offering a network compatible with the device.

AT&T issued this statement to MacRumors:

Beginning Sunday, April 8, we will offer qualifying customers the ability to unlock their AT&T iPhones. The only requirements are that a customer’s account must be in good standing, their device cannot be associated with a current and active term commitment on an AT&T customer account, and they need to have fulfilled their contract term, upgraded under one of our upgrade policies or paid an early termination fee.

Last month, 9to5Mac reported that AT&T had agreed to unlock a user's off-contract iPhone 3GS under a "special one-time exception" after the user sent an email to Apple CEO Tim Cook about the issue. AT&T had previously refused to unlock the device, which the customer wanted to continue to use after moving to Canada, but relented after being contacted via Cook's office.

There have been many different hacks to unlock iPhones over the years, but this policy change will make it extremely easy for AT&T customers to legitimately and permanently unlock their iPhones for use on any network.
