I received 5 text messages today from at&t saying that i have gone over my data usage. one at 4 am saying I'm at 65%, one at 7am saying I'm at 100%, and then one at 8 saying i was over. then i received two more in the afternoon saying that i am WAY over. This is impossible because when i use the phone i am on WiFi and i haven't used the 3g all day. anyone have an clue why it is racking up. I've looked through the post on this site and turned my WiFi sleep policy to never and disabled background data. So I'm hoping that does the trick. if there's anything else i can do please let me know before my bill gets out of control!
