If you had your hopes set on getting a Kindle this holiday season, I hate to break it to you but you may be outta luck. Not only because they are sold out till after Christmas, but because you may not get wireless connectivity where you live, making your Kindle virtually useless. Gizmodo has noted that the Kindle, which is dependent on the Sprint network, will only work in or near the green zones in the map below. Therefore, if you currently reside in one of the vast majority of white regions, don't bother expensing out on one just yet. Let's just hope Sprint improves their coverage in the near future to compensate for the popularity of the Kindle. Just to be on the safe side you can also check to see if you are included in the coverage zones.
