1) Try and downgrade back to 3.0 from DFU mode (probably won't work)
2) Register as a developer, pay your $100 and wait for them to process your application
3) Buy a new phone
4) Follow SilentPanda's advice.

No offence meant, but how could you think you were registered as a developer if you weren't? :confused:

You can put the iPhoen in DFU mode and you can get the UDID that way. I know how it's done on a Mac, just not on Windows. Do a google search and you should be able to discover how to do it on a Windows PC.

I don't understand what you've done :confused:
He downloaded OS 4.0 and installed it on his only iPhone. He's not a paid-registered Developer and his UDID is not on file with a paid-registered Developer so his phone is bricked until his UDID gets on file with a Developer.

Just as Apple did with OS 3.0, after updating to the Beta OS, you cannot revert back to an earlier OS.

download 3.x OS, hold ALT key - click on restore button and load that OS instead of trying to load the current one which saved somewhere in iTunes folder - this should work, because it holds only factory settings

Yep, you can not go back. But I registered my self somewhere in late 2009, and than I 'just' cancelled it. I thought it would remain for one year.
