Apple today released a new version of iTunes for the Mac and Windows that brings compatibility for the newly-released iOS 6 developer beta. During the WWDC keynote earlier today Apple unveiled iOS 6 to the world, the first developer preview has been made available. You’ll need the new iTunes 10.6.3 before you can install iOS 6 on any of your devices.
There are some other bug fixes and improvements packed into iTunes 10.6.3, and everyone is encouraged to update now.
