Looking for a little help. My wife and I both have Iphone 4s. We have both always been around the 1GB range for data usage in a month. If anyone pushes close to the 2 GB range it is myself, since I use the data a whole lot more than she does. For some reason this month her data usage spike to 7GB...she doesn't watch movies, use pandora or stream. So i'm lost at what the problem could be. I tried calling ATT and they said there is some app pulling data in the background. She does use Facebook so was wondering if anyone thinks this could be the culprit. Im going to close all the apps on her phone and reset the usage data on the phone but other than that I'm lost at what it could be.
