Sony’s Fast Forward Facebook campaign has come to its conclusion, and it has announced the Xperia Miro. The campaign started on Monday, when Sony put a countdown clock up on its official Facebook page, along with a fast forward button. When clicked, it shaved a few seconds off the time remaining, promising that when it reached zero a new Xperia phone would be revealed.

The Xperia Miro appeared after 25,941 people sped up time with the fast forward button, and it certainly lives up to the “fun, social and colorful” tagline. But as with everything that’s not a quad-core, $800 device these days, it has prompted an angry response from those who expected something else.

What a shame that after an innovative prelude to the Miro’s unveiling, the Facebook comments are all bemoaning the fact it’s not a top-of-the-range handset, despite it having an interesting connection with Facebook itself.

It’s not all that dissimilar to the Xperia Sola, but does fall beneath it in the range, although Sony has yet to reveal the entire spec sheet. What it has said is the Xperia Miro has a 3.5-inch touchscreen, a 5-megapixel camera that can shoot video at 30fps (but at an unknown resolution) and Android 4.0 Ice Cream Sandwich.

Also featured is a forward-facing video call camera, DLNA connectivity, Sony’s xLoud audio technology and a battery that Sony promises is large and primed for “longer usage.” The phone will be available in several colors: Black, black and pink, white, and white with gold.

So why did Sony chose Facebook to launch the Miro? It’s because the social network has been integrated into Sony’s version of Android, right down to being able to customize the notification light to change color for certain Facebook updates. Sony’s blurb calls the Miro an “Xperia with Facebook” phone, and says it’s “easier and faster to like, comment and share” using the device.

More details should be announced about how this will work, along with the complete Miro spec list during the day, as the timer expired very early in the morning in the UK, the time zone in which the campaign was launched.
