As the mobile multimedia landscape evolves due to the increasing availability of hi-speed networks, Radar, the new web-based photo-sharing service for your phone and PC, is a natural step. Much like Shozu with Flickr built in, the site also has a social networking element. Once you join the Radar community and upload pictures by sending them to an email address, you'll be able to have "visual conversations" by posting and receiving images that you view on a mobile browser or PC. Snaps are immediately available and you can add comments, which can initiate threaded conversations—if you want to be that "in touch."
