I'm sure this has been asked before but I'm new so sorry if it's an old question... So I heard you can put the iPhone 3G and 3GS on Prepaid or Pay-As-You-Go for AT&T. And I just won a 3G on eBay and bought a Prepaid SIM also and I'm waiting for them to arrive. So I wanted to know if anyone is using it on prepaid as well? And if it works. Like, as of today. Also, I heard you have to provide an IMEI number when you activate the SIM... So can I buy a Nokia 2320 which is a prepaid AT&T phone and use that IMEI number to activate the SIM and then insert the SIM in the iPhone? Please answer all questions. Thank you guys!
