Mobile content portal FunMobility has unveiled MyShow, which it says is the first user-generated mobile slideshow publishing application. MyShow is accessible both on the Web and on mobile, so users can browse content, create slideshows and share their "life stream" from anywhere.

The app lets users automatically put together a slideshow around pictures stored in a camera phone, personalize a mobile slideshow with text and background music and upload pictures from the MyShow Web site to add to a mobile slideshow or create the slideshow on a PC. There's also a MyShow widget that they can embed on their Facebook, MySpace or other social networking site.

FunMobility said MyShow will debut with a U.S. carrier by April 30, but it didn't specify which carrier that would be or when other operators might pick it up.
