So I went to the apple store with my unlocked iPhone and asked if a problem I had was an actual "problem". My home button is a little loose, and the guy started checking it, and since its not jailbroken he didnt notice any weird apps, but once he saw the t-mobile part he just gave me my phone back and didnt say anything. I didnt even want to get a new one, I just wanted to know if it was a problem so that I can keep my BlackBerry as backup just incase. Do you guys think that if my iPhone did brake, I could swap the SIM card with someone that has an ATT iPhone and just put it in mine while I am at the apple store?
