iPhone 4S CDMA Roaming

Will the new iphone 4S allow for domestic CDMA roaming when a GSM (AT&T) customer? The building I work in does not get cell service so they have installed CDMA (Verizon) repeaters in the building. If you have a Verizon phone you can get service anything else and you are out of luck. It is repeating the 800mhz CMDA band. I am an AT&T customer and I am wondering if the new 4S phone will work on the repeaters in the building via network roaming.

Probably not. It takes an agreement between Verizon and ATT. That is probably not going to happen.

I'd be very surprised if AT&T has a roaming agreement with Verizon, since they use different technology. Also, I'd guess that as long as a SIM card is in the phone, it will use GSM and not swap to CDMA. I don't think it would work.
