My iPad 2 has simply stopped syncing to itunes. I can still sync my iphone, but syncing ipad 2 has no effect at all. It creates a backup and then simply says that the sync is finished without doing any thing at all. I can still transfer files to different applications . For example, i can transfer some movies to CineXPlayer but cannot remove any app from the ipad 2 or even install any app on it through itunes.
