Is there a nano sim to regular sim adapter?

I want to get an iPhone 5 sometime in the future but for now I'm just going to keep my Samsung Infuse which takes a regular sim card. I used to have Straight Talk but they throttle data, so I'm going to go with att. I want to just get a nano sim card from them and buy an adapter that will let me use the nano sim card in my Infuse. My question is, is there an adapter that exist and will the nano sim card work in my Infuse?
