Photos of what has been claimed to be a nano-SIM tray for the next-generation iPhone have surfaced several times this month, and repair firm SmartPhone Medic now posts a video comparison (via Cydia Blog) of several next-generation iPhone parts including the nano-SIM tray and external buttons compared to the corresponding parts from the iPhone 4S.
The comparison of SIM trays demonstrates how the micro-SIM used in the iPhone 4S/4 does not fit in the smaller tray that is reportedly being used in the next-generation iPhone. Like the nano-SIM tray, other parts shown in the video including the sleep/wake button, volume buttons, and mute switch are notably of a "gunmetal grey" color distinct from the silver color seen on the iPhone 4S. The video also shows the home button that was the first next-generation iPhone part to leak back in late April.
Update: The video has been removed.
Update 2: The video is now available once again.
