It looks like another sweet handset is making its way to Best Buy Mobile and will be exclusive to the mega-retailer. So, before you jump out of your seat and head to Best Buy, let us make this clear: The black Sony Ericsson Xperia X1a is only available online! We scooped you earlier this week when we learned that the silver X1a was coming to Best Buy stores around the country and now that we know pre-orders start November 13 from Sony as well, the streets are obviously going to be flooded with silver models. At $800 a pop, who wouldn’t get one? If you want to separate yourself from the inevitable hoards of silver X1a owners, black is the only way to go. No solid date for when it’s going to show up online and become available yet, but we imagine it’ll be around the same time the silver model hits brick and mortar Best Buys. So is anyone going to log on and pick one of these up when it’s available? Hit the jump for a bigger shot.
