Thank you Gasai!
I apologize, I am a little new at this...
Right now I have CM7 installed (just a few days ago actually), I have clockwordmod installed, and root.
Can I simply flash the CM9 bin directly by downloading it from that link, transferring it to my D2 Global SDCard,
reboot into recovery mode, make backup, reset to factory defaults/clear cache, and finally, apply the .zip file.
This is my normal procedure, but just want to make sure I don't need to do anything else like flash back to stock
firmware, eliminate CM7, etc
