Blonde 2.0 for Mashables.com brings us news that mobile p2p VoIP provider fring has released it’s API for third party developers.

This will enable others to develop new applications and add-ons for the fring platform.

The fring platform supports mobile devices such as the Symbian Series 60, Sony Ericsson UIQ, Windows Mobile 5 & 6 and the iPhone.

As a network, fring also integrates with Skype, AIM, Twitter, Google Talk and the industry standard SIP protocol.

Picked up on Surya Andreas’ blog, we have an article detailing his trials and tribulations with testing out potential Voice over IP client candidates for his Symbian/UIQ based mobile phone.

Fring, Nimbuzz, Truphone and Gizmo are mentioned along with Skype and I-Skoot. He seems to hold Fring in the best regard at the moment for it’s general all-round abilities.
