Apple released a new iTunes update today and it is expected to resolve some nagging issues users have been experiencing while syncing and previewing video. Among the notable fixes, iTunes 10.2.2 addresses an issue where iTunes hangs when syncing an iPad, another issue where syncing pictures takes forever, and a problem where video previews in the iTunes Store skip while playing. The update also tweaks iTune's overall stability and performance. You can update either within the program itself or download it from the Apple iTunes Download page.
