Its painfully obvious Unkn0wn is attempting to throw everyone off track; how do I know? Simple:
#1 These hacks are not new, this stuff has been around since CoD4, you even said it yourself in the first post Fletcher. CoD's core programming has not changed much over the years, its just evolved, meaning the hack is the same.
#2 As someone else mentioned, his "little bird" hack is exactly the same as it is in the iHc patch creator program, which has been around a hell of a lot longer than MW2 eexploits on the PS3.
#3 This "HDD" method we're all attempting is the exact same way its being done on Xbox (not exactly the same, but as far as editing the patch). They JTAG their box, and mod a patch. Where is the patch stored on your PS3? Not on your flash drive, not on your bluetooth headset, and no, not on your SD card. Its stored on your HDD and thats exactly what you need to do to hack the game, decrypt the damn thing, find the patch file, and edit it.
Its not a hard concept to grasp, and the main reason so many people have not done this yet is simply because you cannot do it on v3.30 firmware, meaning you would need an older PS3, something barely anyone (especially on a website designed for online cheating/glitching [who would need the latest firmware to even play online]) would have.
Thanks The End u put it very well and that woz me sayin about the bird and other stuff
