Skype 4.0 improves stability, accessibility

Skype has released version 4.0 of its iOS apps, focused on accessibility and stability improvements. The new version of Skype allows users to move their own video preview window during a video call and the iPhone/iPod touch version includes an updated design for the contacts and messages view and a new sign-in screen. Skype will also now automatically restart if it unexpectedly shuts down for whatever reason, and the update includes a number of other stability improvements and bug fixes. iPhone and iPad versions are available separately from the App Store as free downloads: Skype for the iPhone and iPod touch requires an iPhone 3GS/4/4S or fourth-generation iPod touch; Skype for iPad is compatible with any iPad model. A device with a front-facing camera is required for video calling, and both versions require iOS 4.3 or later.
