Skype has launched a major update to their mobile application for the iPhone platform.

It now allows for calls made over the 3G network.

Till then you can make all the calls you want to make on 3G for free.

– Near CD-quality sound for Skype-to-Skype calls using wideband audio (SILK codec) on iPhone 3GS and 2nd generation iPod touch.

– Enhanced call quality indicator.

– Improved start-up time.

– Fast access to the dial pad from iPhone home screen.
