Just downloaded RC4 today. Installed, went through the steps and successfully booted up my ipt2g MC. I then clicked the "loader" app to install Cydia. And well, what do you know, my iPod locked on me just as I was in the process of downloading Cydia. Now when i try click its icon, it does nothing. If I try to install Cydia again through the loader icon. It just says "Cydia is already installed". Any help would be appreciated. I would like to avoid doing a restore if possible (seeing how I have half of my ipod filled up already), but if it must be done, then so be it.
