The 10.2.2 update addressed an issue where iTunes could become unresponsive when syncing an iPad, and fixed a problem where photo syncing could take far longer than it should. It also fixed an issue that could cause video previews to skip when viewed in the iTunes application, and fixed other stability and performance issues.
Along with the syncing and performance issue fixes, the update also patched a security flaw for Windows users where a man-in-the-middle attack when browsing the iTunes Store could lead to application crashes and unauthorized code execution.
The iTunes 10.2.2 update is free and available via Apple’s Software Update application, or as a downloadable installer at the Apple Web site.
