For all you iPhone 4 users in the UK who are waiting for your free iPhone 4 bumper case or for a full refund if you have already purchased the case, Apple has now apparently sent out emails to all iPhone 4 owners in the UK informing them the program is now open.

According to Rik Henderson over on Pocket-lint, in order for UK iPhone 4 users to order a bumper case they need to download the same iPhone 4 case program which is available in the United States to customers via the App Store, and when you open iTunes you will be offered Apple’s official black bumper case along with a variety of other cases.

Apparently Apple are not offering the option to get a free bumper case in a different colour, although there are cases on offer from the likes of Griffin, Incase and Belkin, but don’t expect your free bumper right away as apparently the bumpers will ship in 3 to 5 weeks and some cases 6 to 8 weeks.

As for the refunds on purchased iPhone 4 bumpers, it is a tad more difficult as it goes by certain factors such as where and when you purchase the case. If you purchased a bumper from O2 UK, you will be required to complete an online rebate form.
