Here, during the live blog they said that the iPhone 4S has 1 GB RAM. Not sure if this is true or not but it's just what I noticed. "iPhone 4S (s is for SHOCKER!) A5, 7x Grafx, 1GB RAM. Epic’s Mike Capp to show Unreal Engine, Infinity Blade “Like an Xbox in your pocket.” Phil is back – increased battery life to 8 hours of talk time. 2:00 Talking antenna: 4S has 14.4 HSDPA. Android fans are laughing right now. World Phone, both CDMA and GSM. Das nice. Camera: Better than other phones, in fact better than some point and shoots 8 megapixel sensor 3264×2448. More pixels!" http://9to5mac.com/2011/10/04/lets-talk-iphone-liveblog/ The quote I posted is about halfway down the page, right under the iPhone 4S bolded headline.
