Fring, the popular free mobile phone application that allows users to make free VOIP calls and chat with contacts of popular instant messengers, is available for iPhone now.
My favourite feature of Fring is its ability to allow us to use Skype on mobiles. I’m using Fring on my Nokia mobile for two past years and able to make make free Skype calls ( and Skype out calls) to my friends who uses Skype.
