All of a sudden this afternoon... My digitizer stopped working. The touchscreen woudn't recoginze any touches

After a while I tried a Hard Reset, hoping it was a software conflict (I have added some software this week).

All that did was make my phone completely unusable, as it is stuck at the Startup/Touchscreen recalibration page.

I've got the BB ESP, but I am concerned b/c the sticker with the ESN fell off a couple weeks ago... I wasn't worried about that, b/c you could always get that information from the phone... Now I can't.

Any ideas???
