Skype iOS apps hit v4.0: improved stability, minor UI tweaks in tow

Everyone's favorite VoIP service, Skype, has rolled out a fresh update to its iPhone / iPod Touch and iPad clients. First off, the Microsoft-owned outfit added a revamped login screen to both iOS applications, and now offers the ability to move your vid preview around the screen -- much like FaceTime does. To go along with the new pair of features, Skype's changelog also notes the app will now automatically restart after a sudden crash, while other undisclosed enhancements were made to improve the overall UI, stability and accessibility. Of note, Skype v4 requires folks to be running iOS 4.3 or later. So, those of you keeping that Cupertino OS current can hit either of the iTunes links below to get the goods, or grab it from the App Store on your device.
