And if you can't get an ota to work later on, that R3L3ASE3ROOT and FOR3V3RROOT tool is a very easy way back to stock. Just use titanium backup to backup all apps and data. When you restore them, dont restore the system apps, I did that and ended up with unnecessary duplicates. After root, use CWM to make a nandroid backup of the stock phone, then you can always have a way back.
Tapped on my Bionic running KIN3TX.
