Nokia confirms first LTE phone

Lumia 900 lands on AT&T's 4G network.

The handset will be one of a bunch of devices coming to the high speed network - a family of six that also includes new Samsung Galaxys and a Sony Xperia.

The Lumia 900 is an evolution of the 800, which is already out. It has a 4.3-inch display and cameras with wide-angle lenses on the front and back, and voice-enabled driving navigation.

"The introduction of the Nokia Lumia 900 with AT&T is another significant milestone in the ongoing rollout of Nokia's global smartphone strategy," said Chris Weber, president of Nokia Americas.

"The Nokia Lumia 900 is designed specifically with the US in mind and the announcement of this collaboration with AT&T, in addition to other recent announcements, signifies a new dawn for Nokia in the US."

AT&T is expanding its LTE network to catch up with Verizon Wireless, which has offered LTE devices for longer. It's currently live in 26 US cities.
