After restoring my ipod from a jailbroken 2.2.1 to a clean 2.2.1, my iPod Touch 2G looks to sync all apps and music correctly. Upon unplugging from my computer, I found that, in fact, none of my music or apps were available. When I plug my iPod back in, I see that all of my music and apps were synced into the "Other" category, taking up about 4GB of nothing. I used a clean (apple provided) firmware to restore, and put my iPod in DFU mode beforehand. Did I miss a certain step in the restore process? I am still able to download apps from within my iPod, but nothing synced seems to stay put. (I am using a Hackintosh, an Intel-based Mac that had run Windows 7 beforehand. Would authorizing by computer be an issue?) Also, I recently restored to 3.0b2, but I am willing to revert back to a clean 2.2.1 if it is needed to fix the issue. Note that this happens on any firmware I restore to.
