Hi everyone. I downloaded a developer version of iOS 4.1 and installed the updated on my iPhone. iTunes will not activate the iPhone because it is not registered with the developer program.

Is there any way for me to go back? i can't do anything since iTunes won't let me proceed.

Try a DFU mode restore to 4.0.1

Plug phone into computer, turn phone off, hold power + home for exactly ten seconds (screen should remain black) release power button but continue to hold home until iTunes display message that it detects a phone in recovery mode.
