Great thanks go to:

Of course Entropy for his awesome brain.

codeworx for giving us CM9 for SGS2.

The CyanogenMod team and all the others involved.

task650 for uploading a complete ROM for you guys to flash a little easier.

Instructions

1. Download Full ROM from above.

2. MAKE A BACKUP to your internal SD!!!!

3. Wipe data/factory reset

4. Wipe cache

5. Wipe Dalvik

6. Flash CM9 Full ROM

7. Reboot and enjoy CM9!

All the usual problem with ICS exist with this kernel (just like the rest of them)

1. Screen turns itself on and off unless you plug in USB or charger

2. Low in-call volume

3. Hard buttons (only menu and home keys work)

4. etc.....

ENJOY!!!!!!!!!!!!
