if you want to record videos, then you can find tons of apps that will allow you to shoot videos.
Jailbreak any iPhone 3G (may work on previous generations, I'm not sure) and use Cydia to download CyCorder. This allows you to record video with your iPhone's camera into .mov format. As far as I am aware (correct me if I'm wrong), you need to SSH into your Jailbroken iPhone to get the videos out (root/var/mobile/Media/Videos), so you may want to get OpenSSH and the iPhone tunnel suite as well.
Through iTunes on your PC or Mac. In there you sync it, with your iPhone.
Sort of. You can download videos through Podcast.
No, you cannot record videos at all with the DSi.

Yes, iPhones can take video. If you go into the camera app, scroll to the video option and hold down the button to film.
When you sync your iPhone with iTunes or Finder, videos can be transferred to your device from your computer, or vice versa, depending on your settings. If you sync videos from your computer, they are stored in the "Videos" app or the "TV" app on iOS devices. Conversely, if you are syncing videos from your iPhone to your computer, they will be saved in the designated location on your computer, typically within the iTunes Media folder or a specific directory you choose.
I would say that a sanyo camcorder is beter than recording videos with the iphone because camcorders have more capabilites than an iphone recording videos.
Simply jailbreak your iPhone 3G or iPhone 3G and install Cycorder.
no you can't record videos on the sanyo katana phone
