So I had a hacked ipod touch 1.1.2. Totally working. I had many great apps installed and was happy with it. I then started having issues with multiple apps, and eventually Installer would crash to springboard. I relized that Categories, Customize, SummerBoard, and the prefrences mod from skylar, were all interfereing with each other. As we speak my Ipod Touch is resotring to 1.1.1 to re-jailbreak it. I now know what apps work, and which dont. Just thought I would share the story with you. I think i just fiddled with it a bit too much.
