Although Apple (AAPL) has reportedly fixed the data overage issue users have been reporting in iOS 6 with the recent 6.0.1 update, PRX Labs believes the bug is still present on a number of devices. As outlined in a blog post, PRX Labs investigated Apple’s Audio Playback frameworks and concluded there is still a bug that is causing devices to download files from the beginning over and over again during file streaming. PRX Labs compared devices running iOS 5 and iOS 6 and noticed that content streaming on the latter downloaded several times whereas files were only downloaded once on iOS 5. PRX Labs says the most users on iOS 6.0.1 will likely see the issue resolved, but several reports on Apple’s discussion boards suggest otherwise.
