i thinki did it right but how do i check to see if i have cm7 an not stock
Tap the contextual menu button
Scroll down to About Phone, tap it
Scroll all the way down, in one of the last last entries, it'll probably say something about CyanogenMod in there if you have CM7. I don't recall offhand what the latest Official OG Droid version is -- I *THINK* its FRG83G for the latest stock, but you'll have to research for 100% certainty.
Hope this helps.
