I just JB my 3G from JB 2.2 to JB 2.2.1, preserve baseband on my aluminum macbook, using a USB 2.0 hub as a bridge. It seemed to have gone well, and when I start it up, I get the pineapple logo, despite having unchecked it. everything is working fine, except there is no cydia or installer icon, and a number of my app store apps, which synced according to iTunes, don't show up, either. I'm really confused, and could use some sage advice.
