Can anyone recommend a good site for switching cellular providers?

My girlfriend has T-Mobile right now, which just isn’t working out for her. Cellphone companies have no problem doing what’s called a “transfer of responsibility”, which means someone else agrees to take over the remainder of the plan.

There are many sites that broker this deal (for a small fee usually). I was just wondering if anyone has used one and what your experiences were.

Or on top of that… if there’s anyone that’d like to take on the remainder of a Fav Five plan on T-Mobile.
