This new iPad 2 back cover from Gear4 is going to appeal to a few people, over 100 million to be precise.
If you are looking to protect the back of your beloved iPad 2 and declare your addiction to one of the most successful games ever, check the three versions out. And if you have an iPhone 4, there are some different Angry Birds designs for you too.
Smart Cover Users Warning
As far as we can tell, these iPad 2 covers do not include a cutout for the Smart Cover hinges, so you may want to check that first before ordering.
