Hi i'm going to sign up for the $30 prepaid plan from t-mobile on the 18th that has a 30MB data package(strictly for messaging only with like meebo app) and i know that the iphone sometimes tries to connect to something if im not mistaken? Just random connects. How would i disable that so that my MB doesn't get eaten? I'd just like more information and if i have to worry about anything stealing my MB plan
