I am looking to get a blackberry from someone but it was previously used as an Alltel phone and I want to use it with Cellular South. It is a CDMA cell phone so it uses the same technology as Cellular South. I want to know if this phone would work fine with Cellular South. If so what do I have to do to get it activated, do I just call and they would be able to activate it over the phone? By the way I am already a cellular south customer.
