Nope they won't do it because it's a Sprint branded phone. CDMA carriers (Verizon, Sprint, USCC) use ESN numbers. Each handset has a unique ESN number that is illegal to change but doable if you want to risk the FCC nailing you if you are caught. Now each phone is programmed to use the specific carrier programming so that you can't just drag and drop like GSM with SIM cards. The ESN has to be in their database for them to activate the phone.
