I haven't posted here in a while, but I thought some of you might get a kick out of this.
I made a CB radio simulator app for iOS, called, simply, "CB". You load it into your iPhone/iPad/iPod touch, choose a channel, hit the push to talk button, and broadcast to the world!
It's an unmoderated, free, anonymous communication channel on the Internet, so of course, there are some bozos out there, but there are a lot of nice folks using it, too. There's a block button for the bozos.
The app is free; there's an upgrade option available, but the main app with all the core functionality is free. Download it and check it out!
It's like DamnPortlanders, but world-wide, in real time, and with audio instead of text.
