The devices able available for update are the Xperia Arc S, Xperia Neo V and Xperia Ray, but only if you live in Sweden, Denmark, Iceland, Finland and Norway. Lucky you!!
If you fall into one of those categories, then you will want to hit up the Sony Mobile Blog. There you will find all the links to the associated pages for download and information. They make special note that not all the software kits are live and you may need to check back a little later. As for the rest of the world, keep your eyes peeled. Updates for other locales should start to appear over the next month or so.
Happy updating and let us know what you think after the excitement dies down a bit.
