Nokia (NYSE: NOK) disclosed plans Monday at the Consumer Electronics Show in Las Vegas to make available an 8-Gbyte version of its multimedia N95 smartphone in the United States.

The N95, optimized for the United States, will support HSDPA cellular technology, which is capable of achieving speeds of between 8 and 10 Mbps. That means the phone will be compatible withAT&T (NYSE: T)'s high-speed network, but it won't work with Verizon (NYSE: VZ) Wireless or Sprint (NYSE: S) since they use different cellular technology.

The 8-Gbyte version is expected to become available at Nokia retailers and the company's flagship stores in the first quarter of this year. But the phone will come with a hefty price tag of $749, likely attracting only a small group of users.

The smartphone is an upgrade to the original 120-Mbyte N95 that Nokia unveiled in 2006. Nokia is calling the new device "the memory-packed big brother" to the original phone. With expanded memory, the N95 offers up to 20 hours of video or up to 6,000 songs, according to Nokia.

It also comes with a 5-megapixel camera, built-in Wi-Fi for accessing the Internet using hotspots in public places or enterprise wireless local area networks, and built-in GPS. The GPS feature can be used with the phone's Nokia Maps application, which offers maps for more than 150 countries.

For better functionality, the N95 slides two ways. It slides to one side to reveal a keypad for dialing and typing, and to another side to reveal controls for playing music or video.

The N95 is part of Nokia's Nseries, a range of high-performance multimedia smartphones intended for entertainment, Web browsing, and messaging.
