Earlier today a picture of the Vietnamese iPhone prototype running OS 4.0 appeared online, letting everyone believe that the guys managed to unlock the device and install an operating firmware on it.
As many users are reporting on the Vietnamese forum though, the image seems to be Photoshopped. The space between bezel and the LCD is too small on a side and there’s a grey stripe that should follow over the whole screen, but it doesn’t.
We’ll keep you posted as we know more.
