Wadja is like a traditional social network, but designed to be viewed on mobile devices. Set up a profile, add friends, upload pictures, comment and check your mail. You can also customize the look of your page by changing the fonts and colors and upload video and audio clips (these can be downloaded again on your friend’s cellphones). Your mobile profile appears at p.wadja.com/username and your mobile number is only be available to people in your network. What’s more, you can check your messages, comments and friend requests by visiting a.wadja.com/username. Another notable addition is a piece of Windows software for editing your mobile profile and uploading media.
