As usual this Skype app for iPad is available to download for free in iTunes App Store. As I have mentioned in the first paragraph that this update for bringing support to Retina Display on the New iPad, if your iPad generation is older than that, no need for you to grab this update.
Having iPad 3 (New iPad) in your hand? Then download Skype app for the new iPad on the iTunes App Store.
Hope this post helps you!
