Do you have an old iPhone sitting around collecting dust? Put it to use and turn it into a webcam that you can use to video chat with friends.

iWebcam lets you take an old iPhone, iPod Touch or iPad (so long as the device has a camera built in) and turn it into a web camera. It works with video chatting apps that require cameras like Skype or Microsoft Live Messenger. It also works for Windows and OSX desktops.

The $4.99 app requires you to download a driver to your computer and an app to the device and connect them wirelessly.  Once you have it installed you can play around with the camera, using it in both landscape and portrait mode and you can determine the quality options.
