Samsung MM-A940

has anyone found a way to put the A970 on a sprint acct, instead of the A940. (sprint guy told me he couldn't activate a 970 b/c they don't offer it) it's the same damn phone though, but the 970 has a few things that are better. does anyone know how to swap a sprint phone by themselves? at nextel, we have to do it, but when i needed to swap the phone numbers on my sprint phones, the care agent told me to type in a number, then type in another number when prompted. does anyone know what the numbers are, cause i'm thinking i may be able to use the same number for the 940, to swap a 970 (ie. lying to the agent and telling him/her i have a 940 and actually doing it on a 970) help me out guys
