Just want to chime in. I got the iPhone 5 on release day, was on wifi the whole night and wake up to a bunch of Verizon alerts saying I went over my data limit. I log into my account and have somehow downloaded 9GB of data over cellular while on wifi! I immediately called up Verizon and reported the issue. I then called Apple and reported it as well.
Apple had me do a restore and then check everything. After a clean restore I turned the phone on and go into cellular data usage and it is literally downloading a couple mb in the few seconds it takes me to go in and out of the cellular data usage setting. I go in and out of the setting 5 or 6 times and this continues until I finally turn off cellular data. The phone just keeps downloading random data on wifi nonstop. I even video taped myself turning the phone off and back on so there were no apps in the background and watching the usage fly up while I was on the phone with Apple.
There is definitely an issue and I'm afraid I'm going to get stuck with the $135 in overages. I have cases open with Apple and Verizon's engineering team and am waiting to hear back. Both Apple and Verizon admitted to having seen this happen before. Verizon keeps reassuring me that I wont have to pay the overages, but I'm not really buying it. I have had 2 new iPads since they came out and an iPhone on a shared data plan and have never gone over my 4GB. This is really frustrating and I'm now using my phone without cellular data turned on since I cant afford to have a $10,000 bill at the end of the month when my phone decides to randomly start downloading data. Any suggestions or ideas would be appreciated, but I'm pretty sure I've tried just about anything.
what does your verizon bill say?
my iphone says over 10GB but my att bill is less than a few hundred mb
