wow! when we found the post of the fring.com startup on TechCrunch, we were really happy. Finally we are able to twitter, skype and gtalk on our iPhones. And even more. Yes, you can also make normal VoIP (SIP) calls through your regular SIP provider like A1 (Austrian network operator), VoipBuster, etc. fring really helps the team on behalf of Mr. Idle to co-work with our international team members more effectively.
If anyone of the fring.com startup asked Mr. Idle for an investment, he would have done it.
