(adsbygoogle = window.adsbygoogle || []).push({}); Someone told me you have to go in one then create your own, when you log off it removes. Is that true? Is there another way to do it?

you can join other peoples speed lobbies, leave and then start your own private match and u'll then have your own speed lobby. But if you go online, quit modern warfare2, turn ps3 off ect.. you will lose your speed hack. Hope this helped

No, once you get infected, create your own private match and invite others. You'll infect everyone who joins.
