I was editing a string in System/Library/CoreServices/Springboard.app to have a black status bar. You are supposed to add a certain string in the info.plist and I put it in there and now my ipod is just constantly refreshing the spring board..then stops...then refreshes a split second later. I tried rebooting and nothing works. I even removed the string and saved it again. It is still doing this! I am so nervous right now. How do I fix this??
