I haven't been paying much attention to jailbreaking in awhile, since I was waiting for the new iPhone to jailbreak my 3G finally. However, I decided to downgrade my 3G from 3.0.1 to 3.0 to see if 3.0.1 might be affecting my GPS and wifi in some way. At any rate, I did the same thing I've done numerous time to downgrade from 3.1.2 to 3.0/3.0.1 and after I was unable to get it to restore without going back to DFU mode and restoring to 3.1.2. So, I started looking for info and came across the "Apple is not signing 3.1.2" stuff. I had thought this was only a problem for the 3GS. Other sites said Apple is not signing anything before 3.1.3. Anyway, is this why my downgrade got FUBAR'ed? Is it true that Apple is signing the firmware for the 3G as well? FYI, I've been able to downgrade without jailbreaking in the past. I know I could jailbreak and do this, but I wanted to know if Apple has done something to keep me from doing the process I used before.
