Nimbuzz announces the UK launch of an application to provide mobile users and online communities with “free calls, chat and more.” Nimbuzz offers an all-in-one solution for free mobile VoIP calling, conference calling, instant messaging, chat and group chat, and photo and file sending across multiple IM communities, including Skype, MSN, Google Talk, Yahoo!, AIM, Jabber and ICQ, plus 23 social networks, including Facebook and Myspace.

The new Nimbuzz mobile VoIP application works worldwide on Nokia Symbian Series 60 devices when connected using a 3G or Wifi network (with a Windows Mobile offering for release in June). For GPRS/EDGE connections, or when using Java-enabled phones, Nimbuzz also offers its “hybrid-VoIP” solution (as used by Skype) - for making international mobile calls at local dial-in cost - in as many as 50 countries.

Nimbuzz is free to download and easy-to-use, but data usage is subject to network operator rates when used on the mobile, unless using a flat-rate data plan.
