The report comes via 9to5Mac. Prior to tomorrow, when you returned an opened product to an Apple Store, you would be charged a 10 percent restocking feem even if you were exchanging it, perhaps for an iPad with more storage.
It may or may not be related to tomorrow's Verizon iPhone announcement, but it's certainly a good time to announce a new policy, with all the publicity ongoing, anyway. It's unclear if this is an across-the-board (meaning all Apple products) policy or not.
