Anybody have a used T-Mobile phone they don't want/need??

Something happened to my sidekick, and I can't charge it.. Tried multiple batteries which charge fine in other phones, but they won't charge in mine.

Now the thing is, my T-Mobile contract expires in like two months.. So I really don't wanna go through buying a whole new phone when we might be switching providers in a couple of months.. I really don't care what it is - I don't need anything fancy..

Let me know!
