I have a 1st gen iPhone that is currently running 2.2 FW. What is the OLDEST version of firmware I can downgrade to? I'd like to go all the way back to 1.0.0 if possible just to play around with it.
Got a tip for us?

Why? All software currently available (app store) only runs on 2.x+. You COULD go all the way back to 1.0 I guess but there are security/stability issues.
I had a thread on this a few weeks ago. I was able to get to firmware 2.0 with iTunes 8.0.2. I used a computer in my basement running Windows XP with iTunes 7.5 to downgrade to 1.1.4, and from then on I was able to get to 1.1.1. The only problem I had was the phone was not activated, and I didn't know what program to use to unlock it, so I updated to 2.2.1..
