EXIF data can be faked which might have you looking at the pictures somewhat skeptically. Even the name of the photographer given credit for the photographs, who in this case is Google software engineer Mehul Agarwal, can be faked in order to mislead the public. Still, where there is smoke there is fire and at this point we can feel confident that the LG E960 will be known as the LG Nexus 4. Now it's just a matter of having the device officially introduced by the Korean manufacturer.
