Cycorder is a program, or "app", for the iPhone that enables you to record and save video with the built in camera. It is only of real use to those with the original iPhone or the iPhone 3G, as the iPhone 3GS and iPhone 4 have native software for video recording.
Cycorder is only available and functional on "jailbroken" iPhones (an iPhone that has been "hacked" into removing restrictions placed on the device by Apple).
Cycorder works with iPhone. So the ONLY way to get back the deleted video is to rely on the backup. If you do not have a backup, it's gone permanently. Sorry.
Cycorder is your answer. It is free but require that you jailbreak your iPhone.
Simply jailbreak your iPhone 3G or iPhone 3G and install Cycorder.
Install Cycorder, which is free, on your jailbroken iPhone 2G or iPhone 3G allow you to record video using your iPhone.
The iPhone 3G already have a camera that is capable of recording video. The inability to record video on the iPhone 3G by default is a software limitation rather than hardware limitation. To record video on an iPhone 3G, simply jailbreak your iPhone 3G and install Cycorder.
This depends on the interpretation of the question. iPhone 3G has a camera that is capable of taking both video and still image, but Apple has limit the iPhone 3G camera to only taking still image. It is possible to take video on the iPhone 3G using Cycorder, but doing so require you to jailbreak your iPhone 3G.
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.
iPhone 2G, iPhone 3G, and iPhone 3GS all have camera that is capable of recording video, however, Apple impose limits on the iPhone 2G and iPhone 3G that disallow video recording, in order to promote the more expensive iPhone 3GS. To record video on iPhone 2G or iPhone 3G, one must jailbreak one's iPhone and install Cycorder, which is available for free.
Yes, iPhones can take video. If you go into the camera app, scroll to the video option and hold down the button to film.
You can take video using iPhone 3G using Cycorder which is available for free, but to do so require that your jailbreak your iPhone 3G. You can also spend your money on the iPhone 3GS so that AT&T can laugh up your money and continue to provide horrible services.
