Is this a reply to ME?
So, that makes my view even more valid, why lock in the states if they all use different Tech???? (That's what you say)
iPhone 4S is multiband GSM and CDMA.
Most GSM phones are multi band, and even in the US there are other (small) GSM providers.
Yes the 4S is multiband but you can't take the At&t version and use it on Verizon and or Sprint and vise versa
