but will i lose all the data on my phone?

NO you won't lose any data because you already have an unlocked bootloader. Go download superuser from the link previously provided, put the file on the sd card. Use fastboot to install recovery:

./fastboot-mac flash recovery twrp-crespo-2.0.0RC0.img, replace the twrp-crespo... with the name of the cwm file you download. Just for you, here is the link again.

Use the link I gave you to download the latest cwm. Use the touch capable one so you can select features via touch instead of keys. Then go into the recovery menu from fastboot. When in recovery, select install zip from sd card, navigate to superuser.zip, install it. Then choose reboot system from cwm. It is that simple.

Right after you get that done, then boot into recovery, select backup and restore and do a backup. This will put a backup of your entire system on the sd card partition. Now you can go and get yourself any custom rom you want and install away without fear of bricking your phone. All you need to do is use recovery to re-install the backup you made and you are back to stock.

No more help after this. You will have to pay someone to root. I can't explain it any simpler than this. Actually the forums on the net explain it the same way. RTFM before crying for more help.

for the last time, it is not because I do not know how to do it, whatever i type wont work after cd /nexussrootICS doens't work and sudo doesn't work either. And yes my phone is in fastboot mode, i put the superuser file on my sd card and yes i replaced the twrp-crespo with the name of the cwm file i downloaded form the website you gave me and yes i got the touch one. keeps saying command not permitted even with sudo

it sounds like you dont have the proper drivers on your computer to run SDK commands on your phone...im using pc and had to load samsung drivers for my nexus s...maybe try with a pc instead of a mac?

does anyone know a way to root *without* wiping data on ICS 4.0.4 stock? - my bootloader isnt unlocked btw...

Can you connect the device and post the output of lspci and dmesg | tail ?

You dont have to put anything to SD. Also, you have to put fastbood-mac in the SAME folder as adb (i.e. platform-tools in android SDK) and the bootloader image you are trying to flash must be in the same folder (or you have to specify the full path)
