Sorry to say this, but I'll have to go with Klaatu on this...
Broken digitizers are currently the most common and the most expensive and difficuilt to replace way for a Pocket PC to die.
Generally, if you have balls and basic skills with a screwdriver, you can replace your digitizer for around $65 using
This Guide .
Have to warn you, though: you screw up - it dies. it's worthless... and judging from the amount of confidence you show, sadly, you're more than likely to screw up.
So either take up on Klaatu's offer and get $50 for it, or take your chances on the repair. It's up to you.
