How do I know this?
The 8530 is a CDMA only phone. Thats the radio network it uses. It will work on Alltel or Verizon or Sprint. That's it.
T-Mobile and AT&T run on GSM radio networks. The two (CDMA and GSM) are not interchangeable. You cannot *under any circumstances* take an 8530 and run it on a GSM network.
The 8830 is a VERY old phone. Although it has both CDMA and GSM, it does not have the GSM frequencies used in North America.
Those are facts. THAT'S HOW I KNOW THIS.
You need to do some research on phones. They are not interchangeable. No matter where you may find them.
