I am new here.
My 7230 hit on ground and it doesn't work as well as before.
I need another wheel,or a dead bb.
Thanks.

It could be possible to take the thumbwheel from a dummy display phone. You can usually find a few on ebay and they're cheap.

Try Pro Mobility:

I think ProMobility is too expensive.
I found a 7100.it is cheap.
But i don't know if 7230's track wheel is as the same as 7100's.
