Re: IMEI change
said by Simba7:SIM card based phones go off of 2 things, the IMEI(the individual number assigned to the phone), and the SIM card ID. The SIM info only links the IMEI to a subscriber, but the phone does not work without an IMEI. AT&T has the power to blacklist IMEI numbers, but they have chosen not to.
Reason for that is different technologies.
You can't exactly change a SIM card in a CDMA phone, because they don't utilize it. As for an at&t phone (GSM), just swap the SIM card.
This worked for me when he switched to VZ and gave me his old Captivate and Aria. Since then, I threw in a StraightTalk SIM card in both of them and they're quite useful.. after I threw on CM9.
