Introduction - What is Skype 2.0 for iPhone? • Based on VoIP clients(Voice over Internet Protocol) – following the footsteps other iPhone VoIP clients such as Fring and iCall. • Skype 2.0 for iPhone is an app that let you use the Skype service to send instant messages and make voice calls for free to other Skype users, and to make low-priced voice calls to cell-phones and landlines around the world.

What is the catch? • Skype’s 3G calling is only on a trial basis for now. • In early 2011, the VoIP company will levy a “Small monthly fee”. (The amount of which remains undecided for now.)
What is the catch?

(Fring even has ‘two way video calling feature’ – a feature Skype 2.0 for iPhone does not have.)
