I just purchased an iPhone 3gs with AT&T. I got the 200 MB package for data because I only use my phone really to check and update my social networking sites. I thought it would be enough, but one night, while I was asleep, my phone used 185 MB in one night ! I called AT&T and they told me to turn off push notifications, and that it would stop, so I did. That day, it continued to go up so I turned the 3G off hoping it would stop. But it still goes up so the last time I spoke with someone at AT&T she told me that Apple updates my iPhone and that there is nothign I can do about it. But, I am connected to my WIFI network at my house, non stop, because I am a stay at home mom, so I do not understand why they are charging me my data when I am on my WIFI network and it shouldn't be using data at all. Does anyone else have this problem!? Is it true Apple updates automatically!?
