Windows Phone users now have access to the Skype Internet calling service.
The "gold version" of the application will be available in April. The beta has been tested and certified for Nokia's Lumia 710 and Lumia 800, HTC's Titan and Radar, and Samsung's Focus S and Focus Flash.
With the Skype for Windows Phone beta users can make free audio and video calls -- excluding potential data charges -- to their Skype contacts over 3G, 4G or Wi-Fi, as long as it is allowed by the operator. When making video calls Skype recommends using a Wi-Fi connection.
A video on YouTube shows how Skype has adapted its user interface to fit with Windows Phone.
Users can also make calls to landlines and mobiles by first paying for Skype Credit. Other features allow users to create and hold group chats, and update their profile and account information.
"This is only the beginning for Skype for Windows Phone...it's just going to get better and better," the blog post said.
