ATT doesn't know what's up. Apple doesn't know what's up. A week ago, Apple advised me to take all of the non original iPhone apps off my phone, which I did, and I'm still using up gobs of data unexplainably. Apple has decided to replace my phone. I had been given the opportunity to replace my phone right away, but I felt it was better to try and be a trooper and see if I could help Apple/ATT solve the problem by holding on to this phone. No dice. Apple has thrown in the towel. They told me ATT said that some app on the phone is responsible for the data usage, but they don't know which one. After the week of just stock iPhone apps resulted in still high data use, Apple decided to send me a new phone. I hate to leave the problem unresolved. And I hate to give in. My question is: is there an app out there, or in development that can get it's hooks into the iOS and other apps on an iPhone that can accurately log data usage specific to individual apps? Dataman can tell you that your using data as a whole, but it doesn't tell you WHICH app is sucking the life out of your data plan. Help!
