How much does a iphone 4 with no contract cost?

AT&T iphone i know with a contract its free but how much without?

$958

It is $499 for the iPhone 4 with 8GB or 16GB (for some reason they are the same price), and $599 for 32GB. This is the unactivated price, which was pulled from Best Buy. See link in source.

$449+tax for the 8 gb, you can only get the 16 or 32 gb of Ebay. Bestbuy nor the Apple store sell the 16 or 32 gb
