If you've got a sizable Kindle ebook library, you should stay far away from Amazon's latest update to its iOS app. In shipping the latest version, apparently the company's QA testers somehow missed a bug that can delete your entire book collection from an iPhone, iPad, or iPod touch. Needless to say, user reviews on Apple's App Store haven't been kind after the issue was discovered. Amazon has since updated the Kindle app's description with a warning urging iOS users to avoid hitting the update button. We'd expect a fixed version of Kindle to arrive sooner than later. In the meantime, we've reached out to Amazon for comment.

Update: Amazon spokesperson Kinley Pearsall writes: "We have identified an issue with the app update that may cause your app to become deregistered. To register, enter your Amazon account e-mail address and password and all your Amazon content will be available in the cloud. We have submitted an update fix for this issue and are working with Apple to release."

Update 2: The fixed version is now available to download in the iTunes App Store. Carry on.
