IPod Touch 5g vs iPhone 4 camera?

I basically need it to be a point and shoot camera but doesn't have to be professional at all. Can someone please tell me the basic differences between the iPod Touch 5g and iPhone 4 cameras, whether or not they are good enough to use as cameras and what you would recommend? Thanks.

Added (1). So is the iTouch camera better overall than the iPhone?

The cameras are about the same, but the iPhone 4 has flash. They are very good for cell phone cameras.

Basically the only difference is that the iPod touch 5G's camera records videos in 1080p vs the 720p of the iPhone 4.
