The original plan was to offer mildly subsidized prices of $399 and $499 for the 16GB and 32GB versions of the iPhone 3G S
to AT&T customers who weren't currently "upgrade eligible," but the carrier's having a change of heart, ostensibly in response to... you know, people wanting to pay less. The new plan is to let anyone with an upgrade date in the months of June, July, August, or September get in on the fully discounted $199 / $299 price points, which should cover a good number of existing 3G owners. Unfortunately, the way the upgrade date is calculated is black magic involving your monthly bill, your credit rating, your contract, and your astrological sign, so you'll need to log in to AT&T's site or call up a rep to figure out the full deal; we're told customers should start to see those new discounts reflected on their accounts as of tomorrow. And don't worry -- anyone who's already preordered will be receiving a full refund for the difference.
