You can buy an unlocked phone or any Cingular branded phone as well as many AT&T branded phones your Sim card will still work in those phones the issue is that AT&T needs to provide you with a newer "3G" compatible Sim card in order to perform an upgrade in their current billing system as AT&T has discontinued support for non 3G Sim cards going forward. The phone would still work if you simply purchased it at retail but you might have to contact AT&Ts Regional Subsidy Unlock Team to unlock it if your Cingular Sim is too old. If your Sim card has a little flame logo and "3G" on it or says 64K on the underside it should work in any current AT&T phone. If it says 32K you probably need to bite the bullet and get the upgrade if its 64K it can be upgraded with any current AT&T phone without 3G support such as the Blackberry 8310 without getting a new sim however.
