I have not used any celluar data since I got the ipad and today was the first day I took it away from my house. As of 2 hours ago it has been on 3g data and I haven't used it. Some how it almost went over my 250mb so I bumped the plan up to 2gb. Anyone have any ideas why? I have two email accounts on it, but they are set to manual and push off so I don't have it bothering me all the time and check it when I want.
