we have 4 lines on our sprint family talk 800 min. no text plan.

i am trying to get change services to AT&T for just one phone. but the phone i want to do that with has a 2 year contract not up till' 2010 and it is 175$ breakage fee to end the contract...one phone i am able to break the contract without payment but she wants to keep her number (for contact purposes). so the one option i had was to drop her service for that phone (not the phone with the 175$ charge) and maybe change the number from phone i am dropping and assign it to another phone on the service/plan . is this possible?
