Hello, I jailbroke my 1st generation Touch at FW 2.2.1. During that time I used Categories to create application folders because the limit in the number of screens. Since then I have upgraded to FW 3.0 through itunes but I did not restore my original 2.2.1 FW prior to the JB. Now when I install applications that I had put into Categories they no longer show up in 3.0. Even if I remove and then restore the applications they still do not show up. I thought at first they were not 3.0 compatible but since then I have downloaded OS 3.0 tested updates to the applications and still they do not show up. I understand I have lost 500MB of storage space by not restoring the original FW. Is that true? Is there any way to remove the jailbroken code and start over again with 3.0 so that my applications show up again?
