If you own an Amazon Kindle Fire you might want to know that software version 6.2.1 is rolling out for your slate now, but there are a couple of things to know about it. For one, the update removes the root from the device and it will make it impossible to re-root the unit with SuperOneClick utility… isn’t that sad?

Amazon must have patched up the ability to root the tablet, at least temporarily. If you’re all about rooting you can avoid connecting to the WiFi network and that’s about it. There’s always the option of installing CyanogenMod, that prevents official auto updates from Amazon, if you’re paranoid. Back to the legit side of things, software version 6.2.1 brings smoother scrolling, passworded protected WiFi access and the option to remove recently used items from the carousel.

Of course, if you want to use custom ROMs you can do it, but there are dangers and bugs associated to such initiatives. Some people out there are buying Kindle Fire hoping that some Android 4.0 Ice Cream Sandwich ROM will come and end their painful experience with the Gingerbread + Amazon layer.
