S3 root and cm mod

[GJ02]

Is anyone running cm10 on their s3?
I'm looking to root mine tomorrow and was wanting some feedback from people who have rooted theirs.
I've been on xda devs and had a look round there, but there are different variants of the s3 and was unsure which variant I should be looking at due to being in the uk
Anyone have a guide on root and cm10 install

Cheers

I'm about to follow this guide

What happens when jellybean is released, will it try and auto download and install it
Also is it easy enough to unroot if need be for warranty purposes
