I have an unlocked 1.1.1 phone that was working fine until right now, when I loaded Installer.app and it asked to be updated. I let it to do that, then I updated to the new Erica's Utils, after that I tried the TIFF Exploit fix but that errored out. So I thought I'd try later.

I quit the Installer App and then the phone hung, so I tried to reset it by pressing power button & home button for 8s, now it won't restart and is stuck on the Apple logo.

Please help me fix this!

Whew! Restored to 1.1.1 in iTunes, then Jailbroke it using jailbreakme.com (which seemed to hang, so I had to restart the phone once and try again. Safari seemed to crash when I clicked to install AppSnap again and took me to the home screen.)

T-Mobile, unlocked, working. Whew!
