Amazon Kindle 3.5 for iOS adds X-ray for extra-detailed searches

Amazon has made a big selling point of X-ray for Kindle books -- but, not surprisingly, for its own platforms first. iOS readers can reclaim some equal footing today now that a Kindle 3.5 update is bringing X-ray to their devices. The addition lets iPad and iPhone bookworms see a map of where characters, places and phrases appear in a given book, whether it's to find a favorite passage or just to keep track of intricate storylines. Very thorough literary types just need to hit the source link for the update they've likely been craving for months.
