SINGAPORE (Reuters) -Japanese-Swedish mobile phone maker Sony Ericsson on Monday unveiled a new third generation technology mobile phone handset which includes a digital music player and a camera.

The joint venture between Japan”s Sony Corp and Sweden”s Ericsson is the world”s fifth-largest handset maker. It focuses on more expensive models and has about a 6.2 percent share of the market.

The new 3G Walkman phone, which has a 2-megapixel camera and allows users to download and browse video games and graphics, will be available at the end of the year.

The latest model is the fourth Sony Ericsson Walkman phone. Sony Ericsson”s W800 Walkman phone was the first phone to use Sony”s revived Walkman brand, first launched in 1979.

The joint venture has been unable to meet demand in Europe for some of its latest models, such as the Walkman phone, because of popular demand, analysts said last month.
