Hello,
My iPhone 3GS was running low in battery and then it went off on its own. Plugged into car charger, usually I would see the charging sign but curiously not this time. Unable to turn on the phone, it's all black. Got home and plug into the computer and it said that it's in recovery mode and it needed to be restored. Attempted to restore but kept on getting unable to restore due to error (21). Did a quick search and have done the followings; (updated all softwares, turned off computer, check USB wire, turned off firewall, created new user, used a different computer....) still unable to restore. screen would turn to white blank screen. Called Apple Support and they had me tried everything again and still nothing. Please help...

MacBook Pro, Mac OS X (10.6.2), iPhone OS 3.1.2
