Apple has begun refunding customers automatically for their purchases of iPhone 4 bumper cases, according to e-mails from the company received by users. Apple said last Friday that it will give away free Bumper cases to all future iPhone 4 purchases, as well as refunding those who bought the cases by now.

Users have been receiving e-mails from Apple saying they have been automatically refunded the price of the bumper case they purchased with their iPhone 4. The move comes in response to the iPhone 4 antenna attenuation problems, which took the company by storm over the past few weeks.

The bumper cases alleviate the iPhone 4 "death grip," which occurs when you touch the phone's antenna black tip on the left side of the metal bezel. An Apple Bumper case cost $29, but it is estimated that a case actually cost Apple around $1 to manufacture.
