ipad stuck on "preparing to sync"
as soon as i plug in the ipad, itunes starts to sync it but stays on "syncing Ipad" (step 1 of 6) preparing to sycn" I can actually do some things, like drag music to the ipad, but it doesn't show that it moves out of the "preparing to sync". I've had to eject and cancel the sync without being able to really get around itunes with my ipad plugged in (ie. to make playlists, etc). The first few syncs were fine -- this only started last month or so. any suggestions? Otherwise the ipad works fine and charges fine via wall, etc. Sort of a pain though if i can't have a home base of a computer to organize all the media. Thanks in advance.
