Need some tips here to solve a mystery. My sister has an iphone 4 and she got a text saying she has exceeded the 3gb limit (we all have unlimited in the family plan). So I looked at her data usage. There are numerous occasions of large amounts of data (30-100 mb plus) being sent late at night. Anywhere from 10:30 to 12 midnight. She says she goes to bed at 9:30 at the latest and uses her iphone as an alarm clock. She checked her icloud settings and said her data and documents is turned off. She does get the warning of "not enough space on icloud" deal sometimes, but I can't imagine that would be it. One night in particular, she had packets of data of 40 mb + that went up 3 times after 11 pm. Of course have gotten nowhere with AT&T so far....
Any thoughts?
