Simple game server

Question

I am looking for a simple game server for the iPhone that I am creating.

The game is based on turns, so I just need a way for players to find other players, and then the server collects and sends queues. This is a simple two-way card game.

If you ever thought of an application with friends ... (Chess with friends, Words with friends), this is the type of server I'm looking for.

Any suggestions for free or low-cost software that I can use
