They have listened long enough to the many complaints about the pricing for early 3G users.

AT&T statement:

Importantly, we want our customers to better understand our wireless device upgrade program. Like most U.S. carriers, we offer a variety of phones that we sell below our actual cost when customers agree to sign service agreements. In general, the more a customer spends with us, the quicker they become eligible for a price break on a new device. For example, iPhone customers who spend more than $99 a month per line with us generally are eligible for an upgrade between 12 and 18 months into their contract.

We also currently offer early upgrade pricing only for iPhone 3G S and iPhone 3G.

All of that said, we’ve been listening to our customers. And since many of our iPhone 3G customers are early adopters and literally weeks shy of being upgrade eligible due to iPhone 3G S launching 11 months after iPhone 3G, we’re extending the window of upgrade eligibility for a limited time.

We’re now pleased to offer our iPhone 3G customers who are upgrade eligible in July, August or September 2009 our best upgrade pricing, beginning Thursday, June 18.

 That means if you are eligible to upgrade in July, Aug, or Sept, then you can get a 16GB 3GS for $199 beginning June 18th.
