Can You Tell Which Photo is iPhone 4 or 3G?

So far the biggest thing to stun me about the wife's new iPhone 4 is the super sharp screen and camera. Displayed on the new phone, the iPhone 4 photo above (I'll tell you which one after the jump) looks stunning.

Here it doesn't seem to be as big a difference despite the original file being twice the size of the 3G photo I took on my phone. Granted, there are some lighting issues in the photo on the right, but looking at the two in Photoshop side by side I wasn't as impressed with the new device's output. What do you think? Can the photogs out there instantly see which is which?
