Just when you thought it was safe to root your Kindle Fire with a single click, Amazon has clamped down on homebrewing enthusiasts. The company has begun pushing out an update for the $199 tablet that breaks the root, disabling the SuperOneClick utility in the process. If you've rooted your tablet and are still running a version of the Amazon-flavored Gingerbread, you're susceptible to the update any time you're connected to a WiFi network. However, if you've already made the leap to another version of Android, such as CM7, you can bypass this and any future software updates. There are some improvements with 6.2.1 though, as smoother scrolling, password protected WiFi use and the ability to remove recently used items from the home screen carousel are among the upgrades.
