Yet Another Mobile VoIP App – Nimbuzz

Nimbuzz is an all-in-one communication software that has just been formally launched. Aside from its own network, it also supports instant messaging and voice calls for popular clients such as, Skype, Google Talk, Windows Live Messenger, Yahoo Messenger, AIM and Jabber. Recent additions include support for true VoIP when making voice calls on S60 devices. Nimbuzz has also created a Communicator widget which allows people to contact mobile Nimbuzz users from a web page.

This certainly looks like a worthwhile app to check out, especially for the VoIP calls.
