no only an iphone
if ur talking about the iphone then yes ipods have no cameras
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.
