An updated edition of Shozu, a free social network aggregator for iPhone and iPod touch, is now available. The upgrade is supposed to further simplify photo uploading, blogging and other mobile interaction with more than 50 Web 2.0 sites, including Facebook, Flickr, Google Blogger, Picasa Web Albums and Twitter , from a single interface. Pictures, for instance, can be transmitted to any number of supported sites simultaneously.

Enhancements include the ability to take and upload high-resolution pictures from within the application, add geo-tags to any photo if desired, make text-only posts to blogging sites, and use ShoZu in five languages. ShoZu has also added new reliability features to ensure smoother photo uploads, easier addition of new Internet destinations, and faster application speed overall.

ShoZu also allows users to change their social network status, have friends’ photostreams and status changes sent to the iPhone, and read and reply to comments posted on their content for a number of the supported social networking sites.

In addition to the iPhone, versions of Shozu are available for about two dozen other mobile handsets. See here to learn more.

You can download the updated iPhone edition from the iTunes App Store here.
