I spent a week on Yo, yo-ing to all the friends of mine who'd downloaded the app. Both of them. Here's how to use it: download, choose a user name, sign in, enter your phone number, wait for Yo to message you a code (no, the message isn't "Yo," much to my dismay), enter the code, find your friends, add your friends, and send them yo. Got all that? Cool.
