You did update to the ICS BETA?
How great does it run? Would you advice me to update too?
I did, I was able to get it to run, but it's a pretty convoluted process to get everything running correctly. It does run almost as well as stock gingerbread, some slow downs, havn't benchmarked it yet, but it feels faster in some areas and slower in others... it's a beta
given you have a unlocked bootloader, a summary of what I had to do
-flash the boot, system, userdata images via fastboot
-flash a custom boot image with a custom recovery built in (fastboot booting didn't work for me, had to flash)
-install latest ICS google bits (market, gmail, gtalk etc)
-install wifi modules
-modify build.prop to support wifi
-reflash stock boot image due to custom boot only being quite hacky and not getting as good performance due to it being based off another device
now like I said it's quite a pain in the ass to get it functional, but it works.
If you aren't much of a tinker'er then I would just wait for the offiical ICS OTA or wait untill a version comes out on wotan server and flash it that way.
