Best PR Firm for iPhone?

We are getting close to launching our third game and I am looking for advice from people that have had success working with a PR Firm and which they used? We have used one in the past and I was not overly impressed, but I will not name names. Also, we plan on a freemium model for this game, if that makes any difference on who to work with. Thanks!

No one has anything to say about this? =)

Maybe you should post in the ios forum

Hmm ok, figured I might get flamed for it not being dev related =)
