MUSIC NEWS - South by Southwest (SXSW) has launched their official mobile social networking and scheduling tool for their 23rd annual event, which begins this Friday (March 13th). Powered by The Social Collective, the mobile site integrates seamlessly with my.SXSW's networking, messaging and calendaring features. Open to registrants of the film, music or interactive events, the site can be accessed by loading sxsw.com in most mobile phone web browsers, including Blackberry, iPhone, Android, Treo and other handsets with modern web-browsing capabilities. You'll then have anywhere/anytime access to all the official films, music showcases, parties, interactive panels and other events via my.SXSW
