Apple has started issuing $30 refunds to iPhone 4 customers who bought a Bumper, report members of MacRumors’ forums.
For customers who bought a Bumper with a credit card, the refunds are automatic; no need to do anything. One forum member reports:
Just got off the phone with Apple to ask if I could get Bumper purchase refunded and he informed me that Apple has begun crediting back credit cards today and will be doing them in batches throughout the week.
