In light of the recent announcement that Microsoft is now starting to prevent owners of modified Xbox 360 consoles, the team behind InFeCtuS saw it fit to claim that their modchip is one of the best solutions to play Xbox 360 online games while still having a modified Xbox 360. They reason that it is because their InFeCtuS modchip can be turned off while you play an original game on Xbox Live.
While qj.net feel that it is important to inform you of this particular development they don't exactly recommend that you try this out. For one thing, folks who have more respect for "the law" might get offended by this. Second, they have yet to confirm if the claim that the modchip will be able to workaround Microsoft's new security net actually works - that is, mod your Xbox 360 and still get you on Xbox Live.
