[mrlachart]

Hy guys,
I really need help with a problem that i'm not sur that can be resolved. I have a htc6900 buy from bell. My screen still find but the touch on in don't work. The problem is that my htc is lock and the only way to unlock it, is to touch the word unlock on the screen but the touch screen not working only the view.
I can't hardreset it because to reloard the software you need to calibrate the pda, but the touch is not working ??? So I wan continue to take my call. I want to backup my pda before send it to htc repair center, but activesync don't want to detect the htc because it lock. "%"/%$%?&**

Please help me boy...
Thanks in advanced to the answere
