It seems that the white iPhone 4, launched last week, has even more differences from the black version. Apart from being thicker by 0.2 mm, it also has a more recessed camera lens and different-looking proximity sensor. It was the back camera lens that is said to have caused the nearly one-year delay of the Great White model. Reportedly, there was an issue caused by the white semi-translucent glass and the flash. This must be the reason behind the more recessed 5 MP camera lens on the back of the device. The proximity sensor has been changed too. Maybe it’s to address the issues with the semi-translucent white front panel.

Saw on a different blog that there were differences, but they didn’t give any reasons for the differences. Your reasoning above makes sense…
