I'm betting it's the Touch... it ain't rocket science...
4(G)S and Touch... iPhone retains same form factor (with a revised antenna that works properly, which had to be a hardware change all along), Touch gets bigger screen... because that would make SENSE on a Touch... iPhone is plenty big enough already.... for a phone. Touch get's 3G option...

Wrong... why not put 3G into Touch similarly to iPad. It has been rumored for some time and actually makes sense.
This is worse idea in all time. How can you think Jobs will delay phone and just put it new chip only. I think you must know nothings about Apple. Is shame.
