Best way to get a Hero

[ds48124]

Don't get me wrong, I love my touch pro, but I feel like every day it wears on me. The problems for me are endless and I've refrained myself from getting a replacement because from the looks of things, it is only a bigger road of hurt.

I'm on a family plan, so I've been trying to think of ways to get a Hero. And I've been thinking if I were to add a new line the phone itself would be only 179$. Now would it technically be possible to cancel the new line and switch the phone over to mine without paying any cancellation fees? And later sell the touch pro in the end getting a Hero for free.
