Earlier this week the existence of a black color variant of the Galaxy S3 was confirmed by retailers in the UK, but we have yet to hear an official announcement from Samsung. That hasn’t stopped T-Mobile from putting the blacked-out device up on their site. It’s hard to deny this one or chalk it up to poor color correction, as the rumored handset appears in a 360 degree rotating animation, showing off some gloss in the process. The animation appears on a page comparing 4G speeds from different US carriers, so it comes with no details describing exactly what we are seeing. If I had to make a bet, though, I’d say a black GS3 might find its way to the magenta network in the near future.
