Root and Cobalt Theme

[Guest DWaldie]

My good lady has agreed to buy me an S2 for Xmas (what a good lady she is). I've been using a rooted Orange San Fransisco and the cobalt them for months and I really like it.

What is the best way to root the phone so I can use cobalt. I'm happy to use a standard ROM initially as long as I can get rid of the bloatware. Any advice greatfully recieved.
