I have a 3G 3.1.3 ipt and was jailbroken several months ago.. The other day when I plugged in my ipod to my usb cable, and started to mess around my ipod, I found out that when I want to activate SBSettings(Slide status bar) I actually launched my dock apps. And when I try to launch my dock apps it actually activates my Sbsettings. (upside down) Hopefully, after I unplugged my ipod, it went back to normal. I played a trick on my friends.Lol Weird Bug.
