Error 1600 when updating to a custom firmware Solved.

If you have been running into some issues updating your custom iOS 4 firmware using pwnage tool in restore mode then there is a simple solution. Instead of putting your phone in DFU mode just do a normal restore directly from itunes while the phone is still on. While holding down the Shift/or Option (Mac) key click restore. This will allow you to search for your custom firmware and restore. Once its complete you will have your phone on the new iOS 4. Remember not to place your phone in DFU mode. Pwnage tool is a tool created only for the mac. But once the firmware is created it can be used on a PC for restoring purposes.
