Please Help! I upgraded my Verizon Iphone 4 to IOS 5 and Jailbroke using redsnow a couple weeks ago. Had no issues and everything was working fine until this morning.....Pulled the phone out of the holster to make a call and at some point the phone must have shut itself down while it was in the holster and attempted to reboot because now all I have is a black screen (it almost appears the phone is off, but if you cover it up, you can see the screen backlight glowing and the phone is on but no logos or anything just a blank black screen) I charged the phone overnight so I know it didn't die and this happened this morning around 9 am and it is still on......I've tried everything to turn it off so that I could re-boot tethered (since this JB is tethered for now) and the phone is totally unresponsive....I've held the home and power buttons down for several minutes trying to restart it with no response....I've tried entering DFU which didn't work assuming since I cant turn it off (it almost seems like it is locked in DFU although I never put it in DFU since it was just sitting the holster) When I got home I plugged it into the computer and nothing recognizes it....I tried a couple different cords and usb ports just to make sure it wasnt a bad cord....Itunes does not see the phone nor does Iphone Browser.....the phone is on but pretty much dead.....What are my options? Please tell me it isn't a brick and there is a way to get into it and restore it....at this point just want to go to the factory ios until an untethered break is out....hoping once the battery dies I can try to plug it in and boot tethered then....any suggestions greatly appreciated since this is my work phone and I can't buy a new one right now..
