Nope I see what you're saying and it makes sense.
i.e original to 3G = small bump
3G to 3GS = medium bump
original to 3GS = big bump
3G to 4G(or whatever it's gonna be called) = big bump
3GS to 4G = small/medium bump
Every year is a small/medium increase over the previous, yet a large increase over the 2 year old model.
Yep thats exactly what i was trying to say. Thanks for making it clear even too me
