Mobile startup Fring has found a smart way to make itself relevant and useful: by integrating Twitter. For those who aren't familiar with it, Fring uses your phone's Internet connection to make VoIP calls, send IMs and use VoIP services (Skype, Google Talk , MSN Messenger and SIP are supported). The addition of Twitter means that you can save on your SMS bill, since Fring works with Wi-Fi or your fixed data plan. So, no extra cost assuming you already have a data plan for your phone.
They've even put up a YouTube video explaining the service (embedded below). So does this make you a Fringing Twitterer? Or a Fritter?
