Apple today announced during a keynote address in San Francisco that its iTunes in the Cloud — or iTunes Match — service now supports 1080p movies. iOS device users will be able to access and sync their movies and television shows across Macs, iPads, iPhones, and iPods. Apple also announced a new version of the Apple TV that includes PhotoStream support. iPhone users can take pictures and the photos will be uploaded to the owner’s Apple TV automatically. Apple also announced iOS 5.1, which will be available for download starting today. The chief new feature in iOS 5.1 is support for the new iTunes Match functions, photo uploads, and the Japanese language for Siri.
