STOCKHOLM, Sweden (AP) _ A joint venture between Sony and Ericsson unveiled its first worldwide product launch on Tuesday, including three cell phones with Java technology enabling users to download games and other applications.

The three phones featuring Java technology will be available in the fall, one of them in the American market, London-based Sony Ericsson Mobile Communications said.

The joint venture announced an agreement with Sun Microsystems in December to use technology based on the Java programming language for its mobile phones.

``Whilst this opens up possibilities in several applications areas, gaming is viewed as one of the services which will gain the most from Java capability,'' the company said.

Sony Ericsson has entered a series of partnerships with the Sony group's entertainment divisions, to make available games, movies, music and digital imaging for the new mobile phones. The company released a phone for the Japanese market in December.

The phones use existing networks, including general packet radio services or GPRS, a medium-speed system that is widely available but little-used.

Jan Wareby, corporate executive vice president, said handsets with the more advanced third-generation technology, which provides more bandwidth, would be available toward the end of the year.

Sweden's wireless equipment maker LM Ericsson and Japanese consumer electronics giant Sony Corp. teamed up in October in an effort to challenge mobile phone market leaders Nokia of Finland and U.S.-based Motorola Corp.
