I know this. Still, when the S came out, it was available unlocked, or through T-Mobile. It would work with ATT's GSM, but not their 3G. Still, the option was there until an ATT frequency version popped up.. I think we're at a point now though, where a single radio chip should be able to support both GSM networks, and the dual CDMA/GSM parts can make it even more widely available.
That would be nice
