Not too jazzed about the prospect of paying up to $500 to upgrade your iPhone 3G to an iPhone 3G S? AT&T has apparently heard your complaints and announced an accelerated upgrade schedule Wednesday for customers who want the new device.

Customers who will be upgrade eligible in July, August, or September 2009 will now qualify starting Friday, June 19, AT&T said.

In general, AT&T provides special upgrade options to customers who pay more than $99 a month for service plans and have completed between 12 and 18 months of their two-year contracts.

Given that the iPhone 3G was only released 11 months ago, very few people currently qualify for an upgrade and would have to pay $399 for a 16GB iPhone 3G S and $499 for the 32GB device.

"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," AT&T said in a statement.

Under this promotion, people who pay more than $99 a month and are set to become eligible in the next few months will be able to buy the 16 GB iPhone 3G S for $199 and the 32GB for $299.
