I just heard about TextPayMe from Steve Smith.  Pretty cool.  It's the next PayPal--you send money to people via a text message from your phone.  Plus, right now, you can win a XBox 360, get $5 for free, and I've heard that you won't get any transaction fees ever if you sign up now.  So what are you waiting for, sign up below and then text me your free $5! :-)
