Got an itchy update trigger finger? If so, your Windows Phone is patiently awaiting. Skype for WP8 just been refreshed to version 2.9, which offers up a couple UI enhancements that should be pretty useful. First, you'll now be able to filter your People list so that you can choose to view only Skype contacts if you prefer; there's also a new contact layout within the app that lets you see more people on one screen. On top of this, you'll also benefit from the obligatory bug fixes and speed improvements -- after all, who doesn't love fewer bugs and getting things done faster? If you do, head straight for the Store and get up to date.
