bOK

bOK is a revolutionary new way of communicating with your friends. The concept is really quite simple: all you need to get started is a mobile phone. After you have signed up for a bOK account and have added the bOK Application to your profile, you can call your friends by clicking the "bOK" link in their profile. You will then receive an incoming call on your cellphone, with your friend on the other line. You can now bOK anyone in the US and Canada for as long as you want, for free!
