WARNING: 360 Firmware Update May Brick Your Console!

Several IGN readers have written us to complain that immediately after downloading the upgrade their console went dead, wouldn't boot up, and displayed an error message. There has been some speculation that the upgrade was meant to kill Xbox 360s that had been modded. But one reader claims that, after his 360 was bricked by the upgrade, he went out and bought a brand new system -- which was also bricked immediately after turning it on and installing the upgrade.

..well a lot of people think that it just happens to people with modded 360's, i got the update and it works fine. Also, Microsoft said that there will be a update to fix the problem within 24 hours...i think it came out already by now
