I was so happy that Fring came available last Sunday. Fring is the only application that provides all Instant Messaging (Skype, AIM MSN Yahoo Google Talk Twitter ICQ), SIP Voice and Skype Voice. And it is free!
But most public who remember Fring in iPhone 1st generation: Fring was always online. For techies: Fring was run as a service. So you could leave your iPhone in your pocket in sleepmode.
