Sprint customers with an iPhone are widely reporting that Wi-Fi calling does not work after installing iOS 11.2 and carrier settings version 31.0.

Hundreds of complaints have surfaced across the web, including the MacRumors discussion forums, Sprint and Apple Support Communities, Twitter, and Reddit, since the software update was released earlier this month.

All models of the iPhone that support Wi-Fi calling appear to be affected, ranging from the iPhone 6 to iPhone 8 Plus, among others.

It's unclear if the issue is due to iOS 11.2 or the updated carrier settings, which support features like Wi-Fi calling and VoLTE. AT&T, Verizon, and T-Mobile customers are not affected, suggesting this is a carrier-specific problem.

Many affected customers have performed basic troubleshooting, such as resetting the iPhone's network settings or simply turning the device off and on again, but there doesn't appear to be a solution that works on iOS 11.2.

As a temporary workaround, some users have downgraded to iOS 11.1.2 and found that Wi-Fi calling becomes functional again.

MacRumors does not have an iPhone on the Sprint network in its possession, so we're unable to reproduce the issue. Sprint directed us towards Apple, which has not responded to multiple requests for comments over the past few days.

Last week, a support representative on Sprint's website relayed that the carrier plans to apply a temporary fix across a limited number of Wi-Fi calling servers while evaluating a long-term solution to the apparent bug. After several days, however, Wi-Fi calling is only working intermittently at best for some customers.

Apple also appears to be collecting data from affected customers who contact the company so that its engineers can investigate the matter, as it routinely does with any potential hardware or software issues.

For those unaware, with Wi-Fi calling, you can make or receive a phone call if you have a Wi-Fi connection in an area with little or no cellular coverage. The feature can be enabled in Settings > Phone > Wi-Fi Calling.

Update: Sprint says it is "actively working to resolve this" issue. A company representative said Sprint will "implement some additional changes" on late December 11 to increase Wi-Fi calling capacity. "This should get us to the optimal performance that is expected," the employee wrote.

Update 2: Sprint issued a carrier update that appears to solve the Wi-Fi calling issue for most Sprint users.

An unofficial iOS app for MyEtherWallet.com rose to the top of the App Store over the weekend, nabbing the third spot in the Finance category after being on the storefront for a little over a week (via TechCrunch). MyEtherWallet.com is a popular service made for storing cryptocurrencies but it doesn't have an official iOS app, so the company tweeted out a warning for users to not be fooled by the "MyEtherWallet" iOS app, as well as asking for Apple to remove it from the App Store.

At the time of writing, MyEtherWallet still remains at #3 on the App Store's Finance chart. The app lists its developer as Nam Le, who has two other iOS apps -- "Panda Warrior: Kung Fu Awesomeness" and "Mr. Beard: Icehole Fishermans" -- and one Apple Watch app called "Wrist Count." MyEtherWallet costs $4.99 and its App Store page says that it allows users to anonymously manage their ethereum wallets, create wallets offline, and store wallet keys securely inside their iPhone.

As the company's mission statement explains, MyEtherWallet.com is a "free, open-source, client-side interface for generating Ethereum wallets & more," so the fake app's $4.99 price tag raises legal questions in addition to the questions of how it got past Apple's app review process in the first place. Tracking service Apptopia told TechCrunch that the app's week-long existence on the App Store has seen around 3,000 downloads so far. Apple has yet to comment on the unofficial app's existence and if it will be allowed to remain on the App Store.

Apps for buying and selling cryptocurrency have become popular recently, with one called "Coinbase" -- this one official -- rising to become the #1 most downloaded free app in the United States iOS App Store last week. This happened after the price of bitcoin rose past $17,000 and saw a price jump of over 20 percent in one day. As the app climbed the App Store charts amid the bitcoin frenzy, Coinbase servers crashed for much of last Thursday, affecting both its website and the iOS app's performance.

Update: Apple appears to have pulled the app from the App Store.

A Reddit post over the weekend has drawn a flurry of interest after an iPhone 6s owner reported that a battery replacement significantly increased the device's performance running iOS 11. The ensuing discussion thread, also picked up by readers in the MacRumors forum, has led to speculation that Apple intentionally slows down older phones to retain a full day's charge if the battery has degraded over time.

According to TeckFire, the author of the original Reddit post, their iPhone had been very slow after updating to iOS 11, especially compared to their brother's iPhone 6 Plus, so they decided to do some research with GeekBench and battery life apps, and ended up replacing the battery.

Wear level was somewhere around 20% on my old battery. I did a Geekbench score, and found I was getting 1466 Single and 2512 Multi. This did not change wether I had low power mode on or off. After changing my battery, I did another test to check if it was just a placebo. Nope. 2526 Single and 4456 Multi. From what I can tell, Apple slows down phones when their battery gets too low, so you can still have a full days charge.

Just over a year ago, Apple launched a repair program for iPhone 6s owners after some users reported their devices were unexpectedly shutting down. Apple said the problem was down to a manufacturing issue affecting a "very small" number of iPhone 6s devices, and offered battery replacements free of charge to owners of devices within a limited serial number range.

Around two months later, Apple released iOS 10.2.1 and said the update resulted in an 80 percent reduction in unexpected shutdowns on iPhone 6s and a 70 percent reduction on iPhone 6 devices. However, Apple explained this was about fixing a more widely reported issue caused by uneven power delivery from older batteries, and claimed it was separate from the manufacturing fault that had caused it to recall a select number of iPhone 6s devices.

This weekend's Reddit thread – running to over 500 comments as of writing – appears to have kicked off a wave of speculation about whether the two shutdown issues are in fact related, and that Apple's fix involves dynamically throttling the phones' maximum clock speeds relative to battery output (voltage), to prevent them from drawing too much power and shutting down.

Reports that the performance of iPhone 6 series models can be improved by replacing the battery aren't entirely new, but the suggestion that Apple is intentionally throttling the performance of older devices, for whatever reason, is bound to cause controversy. We've contacted Apple for comment or clarification.

In the meantime, users interested in checking their phone's performance are also using the free CpuDasherX app to compare running clock speeds (a factory iPhone 6s comes in at 1,848MHz, for example). Let us know your findings in the comments below. Lastly, it's worth noting that DIY iPhone battery replacements or repairs performed by a third party will void any Apple warranty still covering said devices.

iPhone X shipping estimates continue to improve on Apple's online store amid the busy holiday shopping season.

Apple's flagship smartphone is now available for delivery within two to four business days on average in the United States, meaning that online orders placed today will arrive at your doorstep by Wednesday to Friday.

The improved timeframe applies to most AT&T, Verizon, Sprint, and SIM-free iPhone X models, while T-Mobile variants are estimated for delivery by December 19, or roughly six business days from today.

The same two to four day delivery estimate is quoted in several other countries where the iPhone X is sold, including Australia, Germany, and the United Kingdom. Elsewhere, December 19 is a common estimate.

iPhone X inventory continues to improve at Apple retail stores around the world as well, with pickup available today in many locations.

Shortly after iPhone X pre-orders began on October 27, shipping estimates for the device extended to 5-6 weeks around the world, but Apple has been able to improve supply earlier than some anticipated.

According to KGI Securities analyst Ming-Chi Kuo, the improved iPhone X shipping estimates are due to better-than-expected improvements in production, rather than a lack of demand for the new device.

All in all, if you are looking to purchase an iPhone X in time for Christmas, there is still some time on your side. If you're debating between buying an iPhone X, iPhone 8, or iPhone 8 Plus, read our comparison guide.

The iPhone X has been available for a little over a month now, which has given consumers time to adjust to the new biometric authentication method, Face ID. Face ID replaces Touch ID, unlocking the iPhone X via a face scan rather than a fingerprint.

In the video below, we decided to take a second look at Face ID after having spent some time with it to see how it measures up to Touch ID and how it compares to similar facial recognition options in devices like the OnePlus 5T.

For the most part, Face ID works well and is at least as quick as Touch ID, but there are some undeniable pain points. When the iPhone X is held in landscape mode, like when you're in bed, Face ID often doesn't work. It can also have trouble when it's flat on a surface and can't get a good read on your face, and when you have sunglasses, a hat, or a scarf covering your face, it can be hit or miss at times.

These points of failure don't apply to some of the other smartphones that use facial recognition techniques. The OnePlus 5T, like devices with facial recognition from Samsung, uses multiple biometric systems with facial recognition paired with a fingerprint sensor.

Face ID is, however, in most ways superior to the facial recognition options used by competing devices, simply because it offers more security. Face ID is using 3D depth sensing with an infrared camera and a dot projector, while companies like OnePlus and Samsung are using 2D methods that rely solely on the front-facing device camera.

Without 3D depth mapping, the OnePlus 5T's Face Unlock feature can be faster than Face ID, but it doesn't work in low light, unlike Face ID, which can work in almost all lighting conditions. It's also more of a convenience feature than a security feature and it's not used for authenticating passwords or mobile payments.

KGI Securities analyst Ming-Chi Kuo has said Face ID is years ahead of similar facial recognition techniques from Android smartphone makers, and that's evident in the functionality divide between the OnePlus 5T and the iPhone X.

Still, some people are having trouble adjusting to Face ID and miss the convenience of certain Touch ID features, like being able to unlock the iPhone regardless of its position.

Love it or hate it, Face ID is here to stay. Rumors already suggest Face ID will roll out to the 2018 iPhones, and we're also hearing that Face ID will expand to additional devices like the iPad Pro in the future.

Apple may be planning to acquire music recognition service Shazam, reports TechCrunch, which would be one of the most high-profile acquisitions Apple has made since it purchased Beats in 2014.

Shazam is a well-known music service that uses machine learning techniques to identify short audio clips from songs, television shows, and more. Shazam operates a standalone app for iOS, macOS, and watchOS, but also has a close relationship with Apple.

Since iOS 8, Shazam has been integrated into Siri, and it's what powers the feature that lets Siri identify songs that are playing aloud. If, for example, there's a specific song on television and you ask Siri "What song is this?" Siri uses Shazam to identify it.

Shazam is integrated with Apple Music, and Apple Music subscribers who Shazam a song can then tap to play it directly in Apple Music and can add it to a Shazam playlist. Shazam also has an augmented reality feature that allows you to find content based on pictures captured with the Shazam app.

One of TechCrunch's sources said the deal could be worth nine figures, while another says Apple may shell out somewhere around $401 million. Both numbers are lower than the $1.02 billion valuation Shazam received during its last funding round in 2015.

Apple and Shazam could sign a deal as soon as this week, with an announcement planned for Monday.

Apple Chief Design Officer Jony Ive is once again taking over management of the design team at Apple according to changes made to Apple's official "Apple Leadership" website.

The site was updated this morning to remove the profiles of Richard Howarth and Alan Dye, who were managing the day-to-day operations at Apple while Ive oversaw all of Apple's design projects, and Bloomberg has confirmed that Ive is once again in direct control of the team as shared by Mark Gurman.

Ive first stepped back from day-to-day management of Apple's design teams in 2015, when he took on the role of "Chief Design Officer." Alan Dye and Richard Howarth were elevated to vice president positions at that time, with Howarth responsible for industrial design and Dye responsible for user interface design.

For the last several years, Ive has been overseeing the design work at Apple Park and at Apple retail stores around the world, which have undergone a transformation under the leadership of Angela Ahrendts. With Apple Park now complete and the retail store design largely established, Ive now has the time to return to his original managerial duties.

Update: An Apple spokesperson has confirmed to Bloomberg that Jony Ive has returned to his management role following the completion of Apple Park: "With the completion of Apple Park, Apple’s design leaders and teams are again reporting directly to Jony Ive, who remains focused purely on design."

Apple marketing chief Phil Schiller recently sat down with Dutch website Bright.nl, where he covered topics like Face ID and augmented reality, which he's discussed several times in interviews over the past few months.

According to Schiller, one of Apple's goals with Face ID is to make security easy enough "that we all want to do it." Apple believes its implementation of Face ID is superior to the facial recognition techniques available in Android phones, which Schiller says "all stink."

"They don't work in all the ways we need Face ID to work. We're very aware that through the years the simple thing, this Home button, that started as the way you click to get to the Home screen, grew into doing so many things for us. We added Touch ID, it took you to the multitasking screen, paged Siri, activated Apple Pay. All through this one mechanical button.

So for Face ID we needed the best way we know of to enable us to easily unlock our device with our face, in a protected way with the Secure Enclave, and support all these other things. We had to solve all of that. Other things that people have tried with face haven't been anything like that. Face ID is a very unique implementation."

Schiller reiterated Apple's Face ID privacy policies, pointing out that developers have no third-party access to Face ID data. As with Touch ID, the facial scan and data points used to unlock your iPhone are stored in the Secure Enclave on the iPhone X. Developers do have access to facial map data through the TrueDepth camera for AR effects, but Schiller says "that's different than Face ID."

According to Schiller, Apple spent a lot of time studying augmented and virtual reality and the ultimate benefit to users. Schiller, like Apple CEO Tim Cook, says VR is a "great solution for specific use cases" while AR has "incredible broad mainstream applications."

Schiller also had a little bit to say about the HomePod delay. HomePod was originally set to launch in December, but in November, Apple said it would be delayed until 2018. "We feel bad we aren't able to deliver HomePod for the holidays," said Schiller. "We're going to take the time to do it right and make sure it's great when it comes out."

Bright.nl asked Schiller if Apple's "Think Different" motto still applies to Apple today, and Schiller took the opportunity to highlight the AirPods, which are a product that have been lauded as one of Apple's best.

They're really two separate computers that you put in your ear. That's quintessential Apple. We tapped into an eternal truth for Apple. It's about as core to the DNA of Apple as you can get. Think Different should stay very close to true for a long time."

Phil Schiller's interview, which goes into more detail on Face ID and HomePod and delves deeper into Apple's core philosophies, can be read in its entirety over at Bright.nl.
