Apple has not disclosed the amount of RAM in the new iPhone 4S, but so far I've heard 512MB and 1GB.

The old (last year's model) iPhone 4 is being discontinued in the 16 and 32GB size (storage capacity), and they are using an 8GB version of the iPhone 4 (again, last year's model) as the entry level iPhone, along with the 8 GB version of the IPhone 3GS.
He was asking about the iPhone 4S, not the iPhone 4.
