The technology is called UMA technology. This feature is supposed to guarantee cell phone users that they can enter a building at any time and when their cellular service drops out, the phone switched to a WiFi network without losing the call.

The Nokia 6301 has a 2 megapizel camera as well as a 2″ QVGA screen, a microSD memory slot, and support for Bluetooth. It is not likely that it will ever appear in the United States but it is expected to be a big seller in Europe where it is launching. It will be available across Europe by the end of Q4.
