Microsoft's Skype acquisition has been relatively quiet, up until now. The Redmond-based company has finally released Skype for Windows Phone, as the video/voice chat program has hit version 1.0.

The private beta has been available since the end of February, but was only at v0.2, but the final v1.0 app has just hit the Marketplace. The new v1.0 Skype app brings the ability to search for and add new contacts, call to landlines, optimizations and the usual improvements. Skype for Windows Phone lets you make video and VoiP calls over both 3G and 4G, as well as Wi-Fi connections.

At the moment, the app has no background functionality which is a bit of a shot in the foot. Not being able to receive calls unless you're in the app is pretty much a show stopper for me. But, if you want to hit up some of that Skype for Windows Phone, you can get the v1.0 in the Marketplace.
