    If i buy a verizon or sprint iPhone 4S they said they will provide a GSM sim card for roaming use, does that mean i will be able to roam on At&t? or is that feature only for when I'm abroad? Also if i buy at&t will i be able to roam on verizon and sprint here in the states?

    Don't know the answer to your first question (but I can guess - NO)

    As for roaming from AT&T onto Verizon/Sprint, definitely no. This footnote on the spec page tells the tale: "CDMA available only if iPhone 4S is sold and activated for use on a CDMA network"

    ok i found the answer to my first question on engadget, it would have been nice to roam on each others networks here in the states as well, instead of international only.

    "As you might have guessed, the specs for Sprint's version perfectly match the Verizon model -- both have an EVDO radio for 3G within the US, and a GSM one for service outside the country. "
