iPhone 4: users that bought bumpers are now being refunded

After the polemics about the antenna problems on the iPhone 4, Apple had to resort to a quick solution by giving users free bumpers and refunded thsoe who had already bought one. And it seems the first users started being refunded now. Some users from Loop and Macworld have confirmed receiving the refund together with a note that says:

“Apple recently announced that iPhone 4 customers who purchased an iPhone 4 Bumper are eligible for a full refund. As of today, we have automatically processed your refund. You have also been refunded for any Shipping or VAT charges which may have been applied to your order”.

No estimates, however, on the number of users that got the refund, or the time that Apple will take to process the requests.
