yes.
Do not do this:
when updating firmware. The worst thing you can do when updating firmware is to not let it cook through, or interrupt the installation, power down and back up. That is just asking for a brick.
Don't second guess the firmware upgrade. Let it do its thing... it will sometimes take awhile, reboot itself to apply the upgrade, and then reboot itself again. The last thing in the world you wanna do is "hey... maybe this isn't working right... I'll try a hard power down and see if that fixes it." Major facepalm there.
yes, i have the 3.1 GHz i5 with 6970M and i got the update.
