The chances of bricking your phone, regardless of what you do, is very very slim. Most things you can do can be fixed by restoring a backup.
So go ahead and root without fear. Just read the instructions thoroughly. Sorry about the text fonts, but most people just skim the instructions. Then they screw up the rooting procedure by missing a step and then think they bricked their phones. Chances are it's a simple fix and you're well on your way of a rooted phone. So again. Make sure you read the instructions thoroughly.
