The global availability of the Sony Xperia Z flagship device is starting to slowly spread out. It's already available in France, Japan and (as of today) in Russia. It will soon hit Spain and Australia within the next few days and/or weeks. There's no official word on a specific launch of the device in the western half of the world. On the US version of its website, it is simply listed as "Coming Soon," but we will keep you guys apprised when we find out for sure.
