For some reason, prototype iPhone pics supposedly from 2006 have been published. You can see a gallery from TheVerge below.
ICEman who tipped this in noted that it resembles the N9 (Or Lumia 800), albeit without the slightly tapering edges. There’s definitely some resemblance.
Who knows what Nokia’s own unpublished protos look like? I know they showcased something that looks like the iPhone 4 way back in 2006 too.
One of the immediate comparisons, especially from ElMu, was that the N9/800 looked like an iPod.
Quite different from the sides and back.
Cheers ICEman for the tip!
