Mac Rumors posted a story that the new iPhone 4S has 512MB of RAM

Last week, the Infinity Blade developer first suggested that the iPhone 4S still had 512MB of RAM, just like the iPhone 4:"I'm still shocked that, with the iPhone 4S, I'm literally running around with a 1080p video camera in my pocket, with an eight megapixel camera, 64GB of hard drive space and an A5 chip with 512MB of memory. This is a really powerful computer, right? The developer would be in a position to know as they had demoed their game on the new iPhone 4S during last week's keynote.
