We have got to hand it to AT&T, as they’ve continued to impress us during this iPhone 3G S pre-launch period. Remember when we told you that iPhone 3G owners would pay a premium for iPhone 3G S at launch? Well there was a backlash on Twitter, Facebook, and just about every other social network you can think of, with iPhone 3G owners demanding that AT&T rethink their upgrade policy for these early adopters. It meant a difference of $200.

Of course, we figured that AT&T would ignore all of this, as iPhone 3G owners are under a contract that they agreed to, and AT&T wasn’t doing anything but making them live up to those contract terms. However, AT&T has pretty much done the unthinkable, and is allowing iPhone 3G customer who are eligible for an early upgrade in July, August, or September to get the best pricing on the iPhone 3G S. In other words, if you bought an iPhone 3G last July, August, or September, you can pick up an iPhone 3G S for the $199/299 pricing model, rather than the $399/499 price that you are supposed to be paying.

Kudos, AT&T.
