The whole point of Microsoft's Selfie app for iPhones is to share your pretty face (albeit an ideal, algorithmically-modified version of it) with the world, but you haven't had an easy way to make that happen for most of the app's existence. A bit ironic, don't you think? Microsoft agrees. It quietly updated Selfie with a sharing feature that makes it almost trivial to indulge in a little public vanity. You can tap one button to post your latest shot directly on Facebook, or another to bring up the iOS sharing dialogue and spread the joy through other apps.
