In May, Skype released an iPhone app which allows users to make calls over 3G data connections. Today, Skype introduced a new version of the app. A new Skype App for iPhone allows to make calls with high quality sound, and supports multitasking.
It is a great news! You can now receive Skype calls while other apps are running. Also during a call, you can keep the conversation going while you switch to another app.
