How can I get my iPhone 4 Bumper case refund from Apple?

Apple has already begun to automatically refund customers who purchased an iPhone 4 Bumper case using a credit card. You can check on the status of your credit card refund on the Apple iPhone 4 Bumper Refund Program website.

Here are instructions for everyone else who needs a refund.

If you purchased a Bumper using cash, check or gift card at the Apple Store:
Bring your receipt to the store by September 30 to receive your refund.

If you used a gift card on the Apple Online store:
A new gift card for the refund amount will be mailed to you automatically.

If you purchased a Bumper at the AT&T Wireless store:
You must fill out and mail this iPhone 4 Bumper rebate coupon. The claim form must be postmarked by September 23. Your rebate will be mailed after the form is processed by Apple.

NOTE: Only mail-in claims for iPhone 4 Bumpers purchased by August 23 at an AT&T store will be honored by Apple.
