A company called eTradeSupply has put up a video showing off what is suppose to be the next gen iPhone.
The new video is not especially more revealing, but does show the backplate in a number of different angles. The narrator also compares it directly to the iPhone 4, showing the relative size. Other features noted:
– Smaller dock port
– Bottom headphone jack
– SIM card slot smaller
– iPhone 5 is thinner than iPhone 4S (though no screen on the iPhone 5)
