Last night, I was messing around with some files in SSH. I deleted the info.plist and info.pliststrings or something like that and then resprung. It was messed up for a while, it flashed between a black screen and the respring loading screen. I pressed lock and the home button, but it stayed that way, so while it was doing that, I went back into WinSCP and put the files back. Then I hooked it up to my PC and held the lockscreen and home button and then it was fine. HOWEVER, now when I turn the ipod off, it does so MUCH faster than before. What's happened? Is this something to be concerned about? Should I restore and rejailbreak or is it not necessary?
