Unresponsive 2G phone can't 'slide to unlock'
Five days ago I upgraded my jailbroken + unlocked 2G iPhone to the 2.2.1 firmware from 2.1. I added Glass Orb theme and a updated a couple of apps. Everything worked fine for a few days but now I'm locked out of my phone stopped at the 'Slide to Unlock' screen because it won't respond to touch. I experienced the problem with unresponsive 'Slide to unlock' yesterday too but could power off and the phone worked again but now 'Slide to Power Off' is similarly unresponsive...I can't even turn the thing off!
I've tried restoring and Quickpwn'ing again to no avail. I'm in Canada on Rogers' network...the Rogers' SIM was installed for the 'pwning' process. Any suggestions for making this phone functional again?
