I have firmware 2.2 on my 16gb 1g touch with jailbreak. It has been working great, but today the itunes apps stopped opening. I haven't tried every single one yet, but 5 that I tried won't run. They look like they are going to start to open, then close back to the home screen. I connected it to my brothers computer today to change a play list, then I added some files to it with DiskAid. What do I have to do to get the apps to work again? Is it a permissions thing that got scrambled?
