Using nightshot on a camcorder fsjk85, a user at the Australian Whirlpool forums, discovered a hidden data matrix code on the left side of the iPhone 3G, according to Engadget.
We're guessing that's where Apple imprints the serial and IMEI numbers of each handset since it can't exactly hide them under a removable battery (cough), but we'll leave it to the rest of you to decode this sneaky tag and solve the mystery once and for all.

(it's just a picture of one of the frames in the movie)
you can see S/N and IMEI too at the SIM Card Tray, you guys don't realize that?
oh by the way, that matrix code is not new,
you can read it yourself with iphone, with program called iMatrix
