I was looking at the print on the back of the iPhone 3G and compared it to the original iPhone and notice there isn't a serial printed on it. I find this rather interesting move on apples part. Whenever I have had my iPhone replaced, they looked at the serial on the back to pull up the info about it. Now they will probably have to go into the about menu. But this brings up another problem. What if the iPhone is completely fried and won't turn on at all? I guess Apple will have to look up the serial by Name or phone number.
