If tech site Greek-iPhone is to be believed, they've got their hands on even more iPhone 5 components, namely an updated camera module. As always we will take it with a grain of salt but the images appear to line up with what many sites and other blogs have already heard regarding the camera getting an upgrade.
This one includes more megapixels (which is probably a given) and a different form factor from the current camera found in the iPhone 4. It's slimmer and has a more rounded shape. We've been hearing that the next generation iPhone would carry a slimmer form factor and this lines up with that theory.
Next generation iPhone part leaks are getting more and more abundant, but that will come to an end when Apple makes an official announcement in the coming weeks.
