iOS 6 bug that might have caused data overages was fixed in iOS 6.0.112
updated your iDevice to the latest build of Apple's mobile OS. In that case, you need to update immediately to make sure that you are not incorrectly billed or throttled.
Apple's own podcasts have been incorrectly downloaded multiple times and apps that use the streaming audio player have had this same problem. A connection error leads the app to think that the stream has stopped when in reality, it hasn't, and the app starts streaming over from the beginning. A playback of a single 30MB episode resulted in the use of over 100MB of data. Using triple the amount of data than expected will end up with your monthly data plan sucking cash right out of your wallet. Again, it doesn't have to be this way. Just update to iOS 6.0.1 and save your hard-earned cash.
The video below shows the stock podcast player in iOS 6 playing "This Week in Tech". The podcast is loaded up at the 36 second mark and starts over from the beginning. If this happened to you, or is still happening to you on iOS 6, drop us a note in the comment box below!
