Last night i was messing around with my touch installing apps from cydia & installer. I turned my touch off and when i went back onto it later, Installer 4.0 when click, starts to open, but then crashes back to the main screen. I am not sure why it keeps doing this, i tried ftp'ing into the touch and doing this: but there is no Installer directory under Library. Do i need to redo my jailbreak? I tried searching cydia but there is no Installer app.
