Still waiting...

(just checked the app store and AT&T GPS app is still around and they charge you 9.99 a month).

My thought on the issue is if you don't want to rebuild the game completely do that players but an ingame subscription (such as done in Chaos and Order), and apple does not allow you to use subscription thru the app store; simply set up a use login on your webpage for paid members.
I think that's been a way all p2p MMO's been done before app world...
You register on a webpage, pay on the webpage, and play the game via game client (which in this case would be an app).
Let me know what ya think about my crazy ideas

You register on a webpage, pay on the webpage, and play the game via game client (which in this case would be an app).

This would be a quick solution to the problem, but you have to think about someone who is browsing the App Store, sees this game and downloads it, and then is prompted to visit an external site to pay... someone. Sounds sketchy, right? That would most likely lead to bad reviews, accusations of a scam, etc. I'm willing to bet most people wouldn't even go to the website.

IMO, the best bet is to be UP FRONT in the app description that there will be IAP's of $1.99 for a month of play so that people who are checking it out aren't misled into thinking it's just another free game. This will lead to a star rating on the App Store that is more reflective of the opinions of people who are actually playing, and all of us here will be giving it 5 stars, I'm sure.

Of course, I don't know which way would bring more attention to the app: having more downloads or having a higher rating.
