How to downgrade your iPhone

Very rarely will you find instructions to downgrade a device, but there are now instructions floating around the Internet, allowing you to downgrade the iPhone from 1.1.1 to 1.0.2. That won’t result in downgrading your baseband, and hence that means you won’t be able to re-unlock an iPhone which has already been upgraded to 1.1.1, but then again it is still 1.0.2 where third party applications are concerned. Currently, iPhone Dev Team is trying to find a way to downgrade the new firmware, allowing people to unlock their phones again. Well, if you’re an AT&T user, there basically isn’t anything to worry about as you did not irk Cupertino’s wrath by dealing with this shady unlocking business.
