For the last two months something odd has happened to my wife's iPhone at some point. Some application goes off and uploads several GB of data; typically at night. Even though the phone is on WiFi, it does this via 3G. If I wasn't on an Unlimited data plan I'd be screwed with a capital F! I still have not figured out what is causing the problem, I thought it was the Garmen GPS app but that wasn't used in the last month, so I don't know what it is.
Is there any way to tell how much data a specific app used?
