Microsoft Responds To 360 Hackers
Microsoft would like to remind you that hacking your console most definitely voids your warranty. From the Eurogamer article: "Modified consoles, Microsoft added, 'will not be eligible for technical support, and the user's warranty will be voided ... the protection of intellectual property rights is a high priority for Microsoft and our partners, one that significantly and positively impacts economic growth, technological innovation, and most importantly, the confidence of customers who count on the integrity and quality of their products.'"
According to this page. The warranty is only 90 days on the 360, which means that if you bought it on or around the launch day, in November, your warranty expired 3 months ago.
To be unbiased, the PS2 also had a 90 day warranty as well. The gamecube has a twelve month warranty.
