[quote name='metaly']Kotaku (and apparently Rockstar) just
posted some explanation for multiplayer that may offer some explanation about ranking up:
I can't remember seeing "Ranked" anywhere, just Quick, Custom, and Party. If it's true you can't play ranked games with friends, then that's pretty lame.
Anyway, a couple more points I found interesting:
I started getting a call from StrandedBrit in one game and couldn't figure out what was going on.

Not sure how useful this will end up being outside of public games, especially if you have to keep the phone out.
That explains why my teammates kept shooting at me while playing Bomb da Base.

My brother has a (gasp!) xbot360 and the phone is set up like player and ranked, so that was for the Xbot version. Nice to have the private chat feature when someone on ur team has a really annoying mic or something, and NO the phone does not have to stay out for the call to continue. I really like that feature. Its better than muting everyone.
Edit-Just logged on to check my rank and sure enough, back to level 2.
