At the 3GSM World Congress in Barcelona, Nokia unveiled the Nokia 6136 UMA device, which can switch seamlessly between GSM and WLAN networks, thus enabling users to make calls via the Internet. The UMA (Unlicensed Mobile Access) technology will enable operators to deliver voice and data services to subscribers over WLAN access networks. In other words, find a WiFi hotspot and make Internet calls over the WiFi connection instead of over the GSM network. The news didn't specify what type of VoIP applications are supported on the Nokia 6136, so it is unclear if this phone supports Skype or any other popular VoIP application

The 6136 is a quad-band phone that will connect to GSM networks at 850, 900, 1800, and 1900MHz, which means it will work in the US and Europe. Two other nifty features include a 1.3 megapixel camera and an FM radio. The Nokia 6136 UMA phone is expected to be available in the second quarter of 2006.
