iPhone 2G: How to downgrade 3.1 to 3.0.1

If you’ve accidentally upgraded to 3.1 on your iPhone 2G, all is not lost. I have been receiving a lot of requests for a solution.

Apple’s firmware releases have not had any detrimental baseband effects on iPhone 2G’s. So it really is just a matter of time before a jailbreak comes around or a downgrade is possible.

If you are part of the few who have upgraded and haven’t been able to use their iPhone and you have a 2G, you are in luck.

Downgrade my iPhone 2G from Firmware 3.1 to 3.0.1
1. Download iTunes 8.2 (MAC/WIN)

2. Shift Click + Restore to Firmware 3.0.1

3. Download/Use Redsn0w (MAC/WIN)

Note: Some people have had success restoring to an already Jailbroken/Unlocked custom firmware of 3.0.1 and then running Redsn0w.
