UK carrier BT today confirmed its plans for "Project Bluephone". The Bluephone is a multi-network handset, compatible with 3G networks, traditional GSM networks, and with Wi-Fi networks, and able to transparently switch between them. When the user is in range of a Wi-Fi base station, the Bluephone will connect to the network that way using VoIP. When out of range, it will automatically search for compatible 3G networks, and if none are found will fall back to any traditional GSM network found, automatically picking the strongest connection. BT plans a limited "soft" rollout of the Bluephone this summer, with a full rollout planned for later in the year.
