I have an unlocked 1.1.1 iPhone and it's been working fine for the past 3 weeks - no problem! I was getting carried away installing 3rd party apps on it last night and at some point something screwed it up. I currently have the screen with my wallpaper image on it (looks totally normal - the time is correct and keeps up, it shows the correct wireless carrier etc.). The problem is, I can't slide to unlock it. It seems to be stuck in some repetitive little pattern where the "shut down spinning circle" in the middle of the screen spins around for a few seconds and then stops. My slide to unlock bar glistens for about 1.5 seconds and then the spinning icon starts again. This is the repetitive little cycle I'm seeing and I can't slide to unlock my phone at all. I've held down the home and the power button together to turn it off and on (original apple logo shows up on the black screen when I do this), but it always goes back to the same problem with the wallpaper and the spinning circle. Not sure if someone else has experience the same or similar problem but I'm obviously wondering what to do about it. I'm able to connect via sftp so is anyone aware of any preference file I could trash or something that would allow my iPhone to get out of this cycle or is it time to restore it to 1.1.1 through iTunes? What would someone suggest the best approach be?
