I am interested in rooting and running JB but I have never rooted my phone before.  Not to get off topic, but in looking at the root thread sticky, it has not been updated in a while and it starts of with an older version of Android.  I'm running the stock upgraded 4.0.4 ICS.  I have read a lot of articles but they all seem to be a little different than what I have and all seem to have comments about problems.  In short, I'm a bit nervous.  Is there a good tutorial somewhere that will step me through the entire process of rooting 4.0.4 and installing CM10 Nightly?  The process just seems very confusing.  Will I loose all my data and apps when I root?  Will I loose them when I install the ROM?  I have already backed up what apps I want to my SD card and moved all my photos and video to the SD.  Just can't get comfortable enough to pull the trigger.
