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.
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.
