I love that when I take pictures with my iPhone 4 the location automatically gets tied to the picture. The problem is the quality isn't up to par with stand alone digital cameras. Are there any cameras that automatically geotag the pictures taken with it?
@StephanieGIS: An interesting option, although it would be more expensive than the Eye-Fi SD card. The combined cost of both the GIS software and a handheld GPS unit would be at least a few hundred dollars, whereas the Eye-Fi card can be bought for $50, and it doubles as a general purpose SD card.
