I just installed the "Sony Sketch EF" font from Cydia. As soon as i applied the font using BytaFont, my phone froze. I turned it off by holding the power and home buttons. Then I tried to boot it back up, and it just hangs on the apple logo. It will sit on the apple logo for quite some time, then the spinning circle you get when you respring will come up, and get stuck above the apple logo. Any ideas on how to fix this? I know I could restore, but I'm not sure if the latest firmware has an untethered jailbreak? My iPhone is on 4.1 with SHSH blobs all the way up to the current firmware in cydia. I would really rather not restore, ( I was waiting on iOS 5 ), i don't have a recent back up but i'll do what i have to. Thanks for any help!
