I bought medal of honor a couple days ago and i want to know if the beta for battlefield 3 is still available?

from what i understand youll get an invitation to the beta if you buy the limited edition medal of honor. i also bought it and didnt find a code so i dont know exactly how youll actually get to the beta (which hasnt been released yet) but if youve bought a new copy of limited edition you should get the beta when it comes out
