So.. Been looking at iOS 4 Gold Master Release reviews, either from youtube reviews or bigger tech news sites.. It appears it's as snappy on the 3GS as the iPhone 4 was when they got their hands on it at WWDC, which is slightly surprising.. But then not so much.. I've been reading some info about this A4 chip, as i wondered why Steve Jobs didn't coin "1GHZ CPU!" every other word like he did the iPad.. My personal guess.. Down-clocked for battery performance.. Equally though i read that the A4 is actually based on the A8 Cortex which the iPhone 3GS already has, so it's almost to the point where it's just a custom version of that: http://www.hirdyman.co.uk/2010/03/01/ars-apple-a4-cpu-is-a-feature-stripped-arm-cortex-a8/ In the iPads case, it's just a stripped down A8 So from where i'm standing and what i've read.. iPhone 4 really isn't going to feature any sort of bump in speed over the 3GS, which is good i think for allot of people waiting for their upgrade date. I'm personally letting the dust settle and until T-Mobile UK bring out pay as you go options, which will see me get rid of my 3GS for the iPhone 4.. But until that day arrives, i'm pretty chuffed that the only major upsides to the iPhone 4 is new design, screen and camera.. And that we won't see any speed reduction. Any thoughts chaps?
