iOS 6 it had and still has many bugs, but one of them could considerably increase the bill you pay monthly to the mobile phone operator. The problem appears in the AV Foundation framework, it affects quite a few applications from the App Store, plus the native ones, and basically generates multiple downloads of podcasts or audio streams. The moment you start watching/downloading a podcast, your connection is interrupted by the bug present in iOS 6, it restarts the download and things repeat, several downloads are open simultaneously, the same is true for audio streams.
Because the ranges of these requests seem to overlap and the requests themselves each carry some overhead, this causes a single download of an MP3 to use significantly more bandwidth than in iOS 5. In one case, the playback of a single 30MB episode caused the transfer of over 100MB of data.
The problem could triple the internet traffic normally done for watching podcasts or listening to music on the internet and if you have a fixed traffic limit in your subscription, you'd better be careful how you use this kind of applications. The company that discovered this bug claims that it has been fixed in iOS 6.0.1 and that in iOS 5 there are no users of the Apple forum says that in iOS 6.0.1 they still encountered the same problem. Apple knows about its existence, if it has not been solved now, it will be solved in a future update, the problem is that no one knows when it will be available.
