I want to host challenge lobbies on mw2. How do i do that? i've heard about the e3 flasher, does that mean i downgrade, put patch and if i update do i host?
or buying a 3.55 ps3, would that work? and could i buy a 3.56 ps3, can i downgrade to 3.55? or if i had a 3.50 ps3 could i upgrade to 3.55 and data transfer? lol, help me please, i really really really want to host challenge lobbies.

The easiest way to do it is by data tranfer from a PS3 on 3.55. you just update the game and put a modified patch in it and than you just data transfer. when you ain't got enough money for a second ps3 you could buy a E3 flasher. This device will make you able to downgrade from firmware 4.00 (current firmware) to a desired firmware (3.55) and then jailbreak the ps3. and then you modify in the patch. and then just update your ps3 again to 4.00
