AT&T announced Wednesday that it would extend full discount pricing to iPhone 3G early adopters "for a limited time." The company said that beginning on June 18th, iPhone 3G owners who would have qualified for a fully discounted upgrade in July, August, or September can take advantage of the fully subsidized price of US$199 or $299 for the new iPhone 3G S models.

"We've been listening to our customers," AT&T said in a statement. "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."

The company said that its various upgrade eligibility tools, like the one found at www.att.com/iPhone, will reflect the change in policy on June 18th -- in other words, if you check now (June 17th, 2009), you'll be given the same upgrade options as before.

"We've listened to our customers," the company wrote, "and hope our response helps answer some of your questions and concerns [about upgrade options]. We are incredibly proud to be the U.S. carrier for the new iPhone 3G S and will work around the clock to be ready on June 19 to serve customers who are interested in the fastest, most powerful iPhone yet."

If you are eligible for the new upgrade options, you can try to get one in-store beginning June 19th, or you can order online with what the firm said will be a 7-14 day wait on delivery.

AT&T said that those who already pre-ordered a new iPhone 3G S at a lower or no-subsidy rate will have their price adjusted when they pick up the device. If you pre-ordered through Apple, AT&T said that Apple will issue a credit for the difference.

The upgrade policy change largely effects those who bought an iPhone 3G in July, August, or September of 2008, and spend more than $99 per month on their plans.
