The original iPhone was 2G, but it was just called 'iPhone' I think. The iPhone 3G and iPhone 3GS models came after.

I remember buying an iPhone 2G when the 3G was already out, and I still have it.

2G isn’t written on the case, but everybody referred to it as “2G” to differentiate it from the newer model.

And in space, the Space Gray iPhone was just called the Gray iPhone.
