Most excitingly, for many Skype users, video calls can now be made between your PC or Mac laptop or desktop and your iOS device. IPod touch 3rd generation and iPad will both be able to receive video calls, but not send them, due to the lack of video-shooting capabilities on those devices. The new Skype for iPhone app will also work with the with the iPhone 3GS, and iPod touch 4th generation with iOS 4.0 or above – although obviously only allowing the caller to send video from the single camera on the back of the phone or iPod in those cases. It's easy to view filtered lists of numbers - for example, you can see all your Skype contacts or just those who are online.'Now, users can make and receive free Skype-to-Skype calls, call mobiles and landlines around the world at very low rates, and now share more moments together with video on Skype for iPhone,' The latest version has been revamped to take advantage of the iPhone 4's high-resolution display, and the buttons are large and clear. Our favourite aspect of the app is how easy it is to use. But Skype generally offered call quality as good as, or better than, that of other VoIP services we've tested. We found there was noticeable distortion at times, and we occasionally experienced a small delay. The downside is that your call is being squished into a data pipe, so the quality isn't as good as with a normal connection. If you call normal phone numbers, you have to pay Skype, but the tariffs are much lower than normal overseas rates. It's great for overseas calling, and it's free if you call other Skype users. That makes for cheap calls, as long as you don't pay too much for your data bundle. Skype makes calls over data, rather than using the mobile-phone network.
