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.
