I own an unlocked/jailbroken first generation iPhone (2G) and I have never EVER had a cellphone contract because of financial issues. I have used prepaid on my iPhone at another country and it was perfect to use it. I live in USA and I'm looking for a way to use prepaid from AT&T (or anything else recommended) but I'm not sure how it works. I tried searching on the forums and Google about this and I'm just confused. Do I buy those GoPhones with the phones including the prepaid sim? Do I just go to an AT&T store and lie about having a RAZR (ect.) then ask them for a prepaid sim only? I'm really not sure what I should do because I'm so unfamiliar with having a phone. If anybody knows anything, please let me know. Thanks for reading.
