I'm an iPhone newb, switched over from Sprint where I had an unlimited data plan. Now that I have a limit I'm concerned I might inadvertently use up all my data. For example, last Friday I turned my phone off while I was at work because I was paranoid that something would trigger a data connection and it would run all day and use up my allotment. I've turned off Push notification and GPS location services. I'm just being paranoid, right? My phone won't connect itself in my purse and use up all my data, that's just crazy, right? Can you help a newbie?
