Nokia ( NOK), the world's No. 1 cell-phone manufacturer, is having problems with one of its new models.

Some of the brand-new model 5800 XpressMusic handsets seem to be having problems connecting to AT&T's ( T) 3G network.

According to a Nokia spokesperson:

"We have learned that some Nokia 5800 XpressMusic devices are having issues with 3G performance. This is a very isolated problem concerning only the North American market and is not specific to any other region or country. Only NY and Chicago are affected by these problems. In both Dallas and Miami 5800 devices are working fine. The investigation is ongoing on the device itself and the network used in these cases.

"We are currently investigating the matter further to find a quick remedy to the situation. Existing customers of the 5800 XpressMusic who experience 3G signal issue with the device are advised to contact Nokia Customer Care.

"Customer satisfaction and product quality are very important to Nokia and we take all quality and customer satisfaction-related issues seriously."

Nokia's First Touchscreen Hits a High Note

One interesting occurrence to note, another Nokia insider told me that some of the affected phones worked perfectly right out of the box and then recently began having problems connecting to the 3G network. That could mean the problem is centered with the carrier and not the physical handsets.

The 5800 is Nokia's first touchscreen handset. It was designed as a music-oriented media phone with dozens of cool features rather than an email message-centric, PDA-type smartphone with music/video features.

In our preliminary tests, I found the phone to be beautifully constructed and a joy to use. I had no problems with my 5800 test sample connecting to AT&T's 3G network.
