Apple has updated its PC and Mac versions of the iTunes desktop all-in-one application for “i” Devices to version 10.2.1 and the major feature is iOS 4.3 compatibility.

Apple announced iOS 4.3 availability and roll-out for March 11 with the occasion of the iPad 2 keynote and the iTunes update is just a confirmation of things to come, as it adds Sync and Home Sharing support for iOS 4.3 powered devices. There’s not much more to the update than that, according to the changelog, and even if iOS 4.3 wasn’t released yesterday as rumoured, you only have to wait two more days at max.
