I have also done this and it works. rrod is not lifetime warrantied thru microsoft. If that was the case there wouldn't be any broken xbox's out there. They did extend the warrranty but it definitely is not lifetime. It usually takes 4-6 weeks and 99% of the time u get a refurb in return. I was impatient the 2 times i've had to get them fixed in the past and just bought an "arcade" version, put all my accesories on it, and sold the one microsoft sent back to me when it arrived.
