It seems that in October 2012 with Apple's new release of iOS 6 there was, or is still a bug. Verizon customers caught it first with data downloads larger than 450MB in some cases, in the middle of the night while the phones owners were fast asleep. AT&T and Apple also admitted that the phones automatically at 2am download data to their servers.
The question is those of us on unlimited plans for years, now being told we are exceeding our data use for the first time, yet usage has not increased according to end users. Other groups are WiFi attached smartphones also being told and charged for substantial over limit charges. Verizon is reversing all charges. Will AT&T?
