The iPhone 4S is available in 16GB, 32GB, and 64GB models. It comes in black or white.
In the U.S., the iPhone 4S is available from AT&T, Sprint, and Verizon. When purchased with a two-year contract, the 16GB model costs $199, the 32GB model costs $299, and the 64GB model costs $399.
I bought AT&T's version of the white, 16GB iPhone 4S (sans contract) from a local Best Buy Mobile location for $699.99 (plus tax).
