last time I jailbroke on 2.0 I had appflow and was able to hide many icons like cydia, installer, and bossprefs itself using bossprefs to hide it. I was still able to access those on appflow I did the same thing as soon as I got 2.1, got bossprefs, hid it. I had a lapse of judgement as I didn't even test out appflow before I hid all the icons. Now appflow crashes so I can't access any of the icons like cydia or bossprefs to delete it. So I now have a jailbroken iPod with no jailbroken features.
