Fring > Skype, by a huge margin.
It connects to far more people over many other services besides Skype.
Because of that you only need one app instead of like 10 apps.
It does video and 3g too, and has for a rather long time.
Quit dinking around with Skype and hacking it and all that hooplah nonsense.
I'm rather surprised no one has mentioned it yet in this thread.
Just get Fring and you won't need Skype or Tango or even GTalk or really any other
communication app since Fring talks to everyone, including Voip, SIP, MSN,
Yahoo, AIM, other Fring people, Skype, GTalk, and ICQ, all for free.
FringOUT is also cheaper than Skype (usually) if you need minutes for landlines too.
So please quit making all these senseless posts, Wen, about Tango and Skype, etc.
when Fring is the real answer anyway, and has been for months.
