while in the middle of the upgrde my dog hit the usb cable and that's when everything went haywire! It had already backed up the applications and data and deleted them. Now the desktop manager doesn't recognize my 8310 and there's no PIN loaded into the BB. The LED blinks twice in red every 2 or 3 seconds. I've removed the battery, sim card and nothing. Can somebody please help before I have to go to AT&T 2morrow and look like a fool!
