Default [Q] Using a GSM phone for a CDMA service?

Before I begin, I'm not certain if I'm in the wrong forum but I'll know eventually..

Is it possible, (if so, how) to use a GSM phone for a CDMA service, Sprint to be exact.

all in all, can i use my tmobile galaxy s2 (unlocked) for my new sprint service?
if so, how can i go about doing that?!?!?!?!
