So, a friend sold me his 3g (with 3.0). He wiped it clean (using the settings/reset).
When i got it, I jailbroke it and then unlocked it. Everything seemed fine. Then I tried to wipe it clean (using settings/reset), but now the problem is that it gets stuck at the apple logo. Seems to keep trying to load, the spinning wheel will appear and go around once before it locks up. After a few minutes, it flashes white, goes dark, and repeats the cycle. It's now been doing that for about 4 hours.
iTunes does not even see that the phone is there; it never shows up. After I unlocked it, I didn't install anything, or even try to run anything.
Sorry for the sarcasm. What I meant was, I can see that I shouldn't have reset it, but I just had no idea what else to even do since it's not responding to anything other than a hard reset.
