All good things must come to an end, and our BlackBerry PlayBook giveaway is no exception. For those of you who haven’t yet entered, BGR is giving away a 16GB BlackBerry PlayBook tablet that will be shipped right to one lucky winner’s door for free. The contest is open to anyone 18 years of age or older, and unlike many of our giveaways, this one is open to anyone, anywhere around the world. You read that right — even if we have to strap this sucker to the back of a dog sled and mush it to you, we’ll make sure it gets there. And don’t forget, five more lucky winners will each receive an SRS iWOW 3D Deluxe pack and an SRS Labs t-shirt as part of a separate giveaway, so iOS device owners should be sure to enter that one, too!
