[quote name='FREAKMIKE3'][quote name='Blustrk98']Swapping the f-ed one for a good one will not work, since stores (and presumably Microsoft) track XBox (and other consoles) sales. They know what store that particular console was purchased at, date, etc. Plus, the Xbox's serial number is on the receipt, making it virtually impossible to pull off a swap.
I would either register the XBox for the warrenty and then wait a while before calling them about the dead box, OR, as dafoomie suggests, you might just sell it (as a DOA) and get another.[/quote]
FYI, Systems are not registered when you send that in anymore. That only lets them know who owns the system. When a system is sold, the serial number is captured at the time of sale and sent to MS, Sony, or Nin. They use that as the 90 days warranty date, though sometimes they will extend it a few weeks.[/quote]
You're right, the fact that they already have the purchase date of your system (via serial number) would negate the 90 day warranty -and since they know you've had it for more than 90 days, I doubt they would let you simply register for the extended warranty at this point.
I would call up Microsoft and ask really nicely, maybe you'll get a cool rep. on the phone who will give you a break. Tell him you really love the XBox, you play it all the time, and that you've learned your lesson and if he can send you the extended warranty you'll buy in on a replacement. Otherwise it's Ebay time baby!
