Kyte has just released its new Mobile Producer app into the App Store . While it doesn't require you have an iPhone 3GS, if you want to take advantage of its best feature, video, then you must have one. And if you do, I think you'll be pretty pleased with how well it works.The app, which is $4.99, is very simple. You boot it up, log in (or create a new account), and you're taken to a screen where you put in a title for your "show" (what you're about to broadcast). Below that are links to add video, a photo, and/or a link. If you choose to add a video you can easily take a new video, or use one you've already shot with your iPhone 3GS. The video capture functionality is fast and works just as well as the iPhone's own video capturing app.
