Will Sprint iPhone 4S work on AT&T?

[Bengal313]

I was thinking about buying the Sprint 32GB white one from a friend. Does this phone have a Micro SIM port? Will GSM carrier like AT@T work on it? I know there isn't an unlock for it yet. But wanted to buy it for future.

Basically I need to know is the AT&T iPhone 4S same as the Sprint? Or are they making one for CDMA and one for GSM?

No, it won't work with AT&T. It's locked to Sprint. The purpose of the sim card is so you can roam on GSM networks in foreign countries. You'll pay the roaming charges to Sprint when you return.
