Here are the details from ABC.
Apple Posts iPhone Credit Instructions
Apple Inc. has begun allowing people who bought iPhones before the higher-end model’s price was abruptly slashed to apply for a $100 store credit.
The company said the credit would be available for people who bought either the $599 8-gigabyte, iPhone or the $499, 4-gigabyte model before Aug. 22. People who bought the phones more recently are eligible for refunds.
Those early buyers must fill out a form on Apple’s Web site to have the retail or online store credit delivered to them electronically. The credit can be redeemed only inside the United States, and cannot be used inside the iTunes store or for Apple store gift cards, according to terms listed on the company’s Web site.
For those of you who, like me, got the iPhone early on, here’s your Apple page link for the credit. Onward Apple shoppers!
