Over the past several months, iTunes users in the U.K. and several other countries have noticed the availability of the welcome screen of iTunes Radio on their devices, hinting at an upcoming release.
As of today, MacRumors has had a few reports from U.K. and Australian users that have been able to access and listen to iTunes Radio on their iPhones. While some MacRumors forum members in the U.K. have been able to access the service, others say that it is not yet available for them. Similar reports are coming in on Reddit and Twitter.
It appears that most of the users that are able to access and use iTunes Radio had recently wiped and restored their devices, which suggests that iTunes Radio may be accessible after an iPhone reactivates. MacRumors is not, however, recommending that users restore their devices, and it's not clear if this is a temporary glitch as Apple prepares for the U.K. launch.

iTunes Radio, which was first announced in June at the Worldwide Developer's Conference and later became available in September alongside the launch of iOS 7, has thus far been limited to listeners in the United States.
In October, Bloomberg suggested Apple would expand the service to Canada, the U.K., Australia, and New Zealand by early 2014, but the service has remained limited to the U.S. throughout January. While some U.K. users receiving access after a restore could indicate an imminent release, a similar situation arose back in October with some users in Canada and the U.K. temporarily able to access the service.
According to Apple’s senior vice president of Internet software and services Eddy Cue, launching iTunes Radio worldwide is a top priority for the company, with Apple ultimately aiming to have the service "in more than 100 countries."
