There is a shop called Communication Center on the Al Nasr Street - Just down the road from Family food center. He carry's all kinds of Palm Phones, Imates, blackberrys and other PDA's. I'm pretty sure if anyone can fix your phone its him.

Plus he has all the newer models if you want pick up a newer model instead of repairing the old one.

The number for the store is 4440340..

Im a regular customer there and they are pretty professional so hopefully this helps !!
