First off. Theres isn't any Challenge lobbies for mw3 yet! If there was mw3 would be a lot strict and you can get banned easier. Trust me I've been in Challenge lobbies on mw2 before, and theres noting to it!
These are illegally and cheating the ranking system. Play the game like any other person.
Yes.
You really can't, not unless you want to go through a lot of downloads that could possibly corrupt your computer and PlayStation 3's data. My friends can host challenge lobbys and they all did theirs using jailbreaks, buying downloads that guarantee challenge lobbys. Believe me, I've tried pretty much everything to get a challenge lobby for free but nothing really works without confusing you,
ya i can and for FREE just send me a message and tell me u saw my name on here my name is ThermalQUIKSCOPE
