I have an elderly friend that he and his wife have 3G iPads. They both got the 250MB plan since they only need email and a few web site visits. For some reason after activation his used all 250MB's in 5 days. He only checked his email once in that time. I spent over and hour with AT&T explaining that it could not have possibly used that much data. They finally gave him a credit and now just 3 days later he's at 50MB and only checked his email 2 times. His wife who uses hers much, much more has only used about 60MB in almost a month. AT&T says the iPad may be defective since the data WAS used. Is this possible that the iPad can randomly use large amounts of 3G data even when asleep?
