Those who find themselves using Skype and rocking a Windows Phone device may want to fire up the Marketplace and grab the latest update. And in a bit of good news for Skype users, the app has dropped the beta tag and landed at version 18.104.22.168. The app, as one would suspect, will allow you to make free and low-priced calls. The user will be able to make voice and video calls as well as send instant messages to other Skype users. And nicely done, Skype for Windows Phone will work over cellular 3G/4G and Wi-Fi connections.
