I have 6 lines with Sprint for my business. 2 of those lines are coming up on the $150 rebate for signing another 2 year agreement. My question is would Sprint get made if I got the phone with a different line then the one i'm using and then after I get the phone put the new one on my number? I think it'd be ok. i'm not signing up for a new contract then terminating it. could be way out of my element though. any thoughts?
