I had to downgrade my itunes from 9.2 down to 9.1.1 in order to jb my 2G Itouch using blackra1n. Now my itunes syncs and backups from my itouch to my windows pc, but i cannot load any new songs or videos (they're grayed out in itunes). I also get an error about "cannot load sync services" or something similar which I'm sure is relate to the problem. I'm wondering if itunes 9.2 will fix this problem. My question is can I or should I upgrade to itunes 9.2 now? Will that mean I have to downgrade again if I have to jb again in the future?
