Google and Nokia to Team Up

"The agreement calls for Nokia to introduce a handheld device that comes loaded with the Mountain View company's Google Talk, an instant messenger and Internet calling service.

Cellular signals will not be used for the calls. Instead, the calls will be made using a wireless Internet network, known as Wi-Fi. Such access is available in many homes and cafes that have Wi-Fi hot spots. Wi-Fi is also increasingly available through civic projects that blanket entire cities with wireless Internet connections.
