Before we even start, obviously this is something that isn’t covered by warranty and may destroy your phone.  Once you go to iOS 5, you cant go back. APPLE WILL LIKELY FIX THIS IN AN UPCOMING iOS 5 UPDATE AND YOU WON’T BE ABLE TO USE YOUR DEVICE (until iOS 5 final is released or a developer adds your phone to his or her device list).

Gizmodo see a video on how to activate an iPhone on iOS without having your device ID provisioned by a developer/Apple.  The exploit uses a combination of Voiceover and the pull down notifications to activate the phone.  The user that found this exploit says the device continues to work after restarts (so you won’t need to activate it every time you restart).
