iPhone 3GS + 12seconds.tv + Twitter = 12cast

What do you get when you mix the new iPhone 3GS, the micro-video site 12Seconds.tv and Twitter? It's a free app called 12cast, and it's the fastest way to send 12-second video straight from your iPhone to Twitter. In case you're not familiar with 12Seconds.tv, it is to YouTube what Twitter was to blogs: a speedy, concise version of a good idea.

Using 12cast is almost ridiculously easy. You put in your Twitter login, turn the phone sideways, and video starts recording automatically. Like 12Seconds.tv, 12cast limits you to 12 seconds of video. When you're done, you can preview it, retake it, title it and send it to Twitter. You can also use 12cast to upload existing short videos that might already be on your phone.
