PocketCam lets you use your iPhone as a wireless webcam for your

Windows-based computer or Mac (OS X 10.5 or above). PocketCam

 automatically forwards video captured by your iPhone camera,

 which can then be used as if they come from a virtual webcam.

 

 

 

PocketCam works with any Windows-based webcam applications,

 including instant message applications such as MSN LIve Messenger,

Skype, AIM, etc.
For Mac users, PocketCam works with any Mac applications that use
QuickTime for video capturing, including GTalk, Skype, and aMSN.
