I just installed OS 2.2.1 over iTunes. When I open XCode, I saw this message in the Organizer: The Developer Disk Image could not be mounted. Xcode could not find an appropriate Developer Disk Image to mount on your iPod. Please contact Apple for the 2.2.1 (5H11a) device support package. This was working perfectly with 2.2.0. I've tried looking for OS 2.2.0 to download and can't find it. Has anyone else had this problem? This is just a stock iPod touch; not jail-broken or anything.
