HTC and Facebook have been developing a Facebook phone that will be unveiled today at the Mobile World Congress in Barcelona, Spain, according to reports.

Users of the new device will be able to access Facebook easily via a dedicated Facebook key with a “F” logo that will enable users to easily upload facebook photos, or share their location when using Google Maps.

“HTC has brought Facebook to these two new devices in an innovative way enabling people to connect and share easily whenever they want, wherever they are,” Henri Moissinac, head of Facebook’s mobile business, commented in a news release.

Jason Mackenzie, president of HTC North America in Bellevue, said Facebook’s logo appears on the special key but “we will not brand this as the Facebook phone or anything.” Mackenzie said the “ChaCha” model, with a 2.6-inch touch-screen and exposed keyboard, will compete with the BlackBerry Curve.

The second model, the Salsa, is a touch-screen-only phone with a 3.4-inch screen. This will be rolled out later in the year.
