An Austrian forumer has discovered, while testing the night mode on his camera, that on the left side of Apple iPhone 3G there is a hidden QR code that is invisible to the naked eye. The dot matrix hidden on the side of the phone is probably the phone's serial and IMEI number, but nothing sure is known of it yet. The codes probably serve only identification purposes and help tracking a hacked device if someone tries to take them to a service center.
