Can anyone host a ps3 mw2 10th lobby for me or get me in one please? or tell me how I host them on PS3?

i can't find one, and neither can i host, but if u can either get me into one, do one for me, or direct me to a tut on how to do it, it be cool! i know u gotta jb your ps3 or something, but mines on 3.66 and i doubt u can jailbreak it :(
