It's technically possible for the iPhone to use it's built-in camera to record video. (even the last generation iPhone was able to do this once you jailbroke your phone) I've never heard anything in the SDK terms of use agreement saying that developers AREN'T allowed to make video recording Apps. Apple could still reject submissions if they deem necessary.

(they may feel that video recording with the camera could make the iPhone too unstable, too much battery consumption, etc) You should find out who created the video app for the 1st gen iPhone and see if they are planning on legally releasing a version for the App Store. Watch this video: And this video. Its gonna happen and soon.its just all about getting it approved for the apple store.but now since you can jailbreak any iphone including the 3G.all kinds of video apps will show up on the net. The hackers say they might be able to get up to 45 FPS!!!! From Engadget: 'Thanks to another set of ambitious iPhone hackers, we've officially got video on Apple's wonder-device (that somehow omitted video to begin with). It's not much right now, but if you want, you can see your phone recording five succulent seconds of real-deal video at around 15 FPS. The developers say this is just a proof of concept, and they've been able to get up to 45 FPS on the device - so hopefully we can expect a more robust version soon (like, say, one that lets you save the recording).
To record your Mac’s screen, open the QuickTime application and click File > New Screen Recording. You can then click the little menu to the right of the Record button and choose whether you want to capture audio from your microphone in the video, too.
Check the video after the break to see the gorgeous work in action.'
