Yahoo Mobile service in the U.S. is available for download or installation since Tuesday.

It is preloaded on the Nokia 6682 and will be loaded onto other Nokia phones and Motorola phones eventually.

Yahoo Mobile is in a joint venture with AT&T and Cingular, launched AT&T Yahoo Mobile, an integrated service that allows Yahoo ID holders to take their Yahoo with them virtually wherever they can get service. The service was first announced at CES.

Through this new mobile phone service the handset is turned into a mini computer, allowing access to Yahoo Mail, Photos, Address Book, Calendar, Messenger, search functions, news, weather, and sports. The user-specific features are integrated with the phone as well, allowing Web access to phone functions in a vice-versa twist.

"We're blurring the lines between the PC and the wireless phone so that consumers can stay in touch, check e-mail, get updates on news and weather?minute to minute, day by day?regardless of where they are or what screen they are watching," said Scott Helbing, AT&T Consumer chief marketing officer.

The Nokia 6682 also comes loaded with an MP3 player, digital voice recorder, data storage capacity, and removable media.
