I have a 1g iPod touch, upgraded to 2.2.1, unjb'd, and my iTunes thinks it's an iPhone. Thus, my music is grayed out, and I cannot manually drag/drop. When I check the "Manually Manage" option, a pop up box comes up asking if I would like to erase and sync with this computer. I click no, and then it reverts to the original grayed out settings. Help to these two problems? Thank you.
