Okay, i had a problem after i downloaded something from rock and resprung to install, when i got to type in my password to unlock a message appeared that something about sbsettings.dylib went wrong and my ipod was really really slow. i had to practically hit my ipod and hold the buttons for like 10 seconds before it actually typed in one letter. after that i went into ifile off of safe mode and then i found sbsettings.dylib located in the MobileSubstrate folder. So i thought if i moved the folder it would work out so i moved the ENTIRE mobile substrate folder and tried to reboot. Now when i try to turn on my ipod it stays at the boot logo for like an hour before turning off. IT WONT BOOT!!! Thanks for any help.
