Looks like it was all a big fakeout by some less than reputable people.
Previously, we mentioned that there could be a mod chip soon that would allow the playing of backups, and whatnot, but now, the sites, icemodchip.com and infinitymods.com are down and removed, and it is expected that we won’t see them again, atleast not for Xbox 360 Mod Chips any time soon.
Sorry to all those that were hopeful.
