Right now I'm under an AT&T family plan (voice only). I'm thinking of buying a used iphone 3G from ebay, and use my current sim card. Here are my questions:

1) Will AT&T find out I'm using an iphone and force me to add data plan? I don't need one since I have access to wifi everywhere on campus.

2) Do I need to activate & jailbreak & unlock the iphone before using it?

Thanks a lot for your help!
