Ustream iPhone App Lets You Stream Live Video - PC World
Over the last year, Ustream has sought to extend its reach into the mobile arena, and the company has introduced video-recording and viewing iPhone apps, but its latest offering allows true live broadcasting to multiple viewers. You can begin recording video on your phone, stream it to the Web, and allow any number of people to watch it as it happens. You can include your GPS location with the broadcast as well.
This is something that I think will make ustream way more useful. I've had an account for years but rarely a chance to use it since you had to be connected to a computer.
