This Is So Cool. My Whole Family Needs This

So today I downloaded probably the coolest application of all time on my iPhone. It's called Tango and it does live video streaming just like a webcam only 100 times easier to setup. My 5 year old niece could figure out how to use this thing, it's that simple. Below is a picture. Natalie called me and that is what I'm seeing on my phone, Adri smiling at me. In the left corner is what she sees, the freeway from my office. If I had an iPhone4 instead of the 3GS we could both be seeing each other's faces but I don't and we don't have money to get new phones right now. So until the next iPhone comes out we'll have to view one person at a time. It's still a way cool app though. Wherever I am at I can show her what I'm seeing. Plus all the sound goes to speaker phone. Where is the "like button"?
