I've upgraded to 2.2 a week ago, and then followed with the necessary QuickPwn.
I noticed some service (reception) issues at first. In areas where i know i get great reception it would say "Searching..." for over long periods of time. I even noticed that it would do a hard reboot on it's own.
Here's the problem i face today. When i hit the home or power button, the screen remains black. So I try at later time thinking it's intermittent... wrong, it's still this way. No problem, I'll plug it into itunes. I have it on vibrate setting and typically when I plug it in to charge, it gives me that vibration to let me know it's connected and charging. This time it did not, i even tried flicking the side switch from speaker to vibrate and it wouldn't respond.
Here's the weird thing... iTunes recognizes my phone and all it's contents (trying to do a backup as we speak). since I cannot see the phone screen, how do I do a reboot on it without doing DFU?
What are my options at this point and have any of you had problems with this?
