Can I create a game and submit to iOS App Store with Unity3d free version?

Hi, I’m completely new to Unity3d and iOS development. Is the unity3d free version sufficient to create a small iOS game and submit it to App Store?

Yes, you just need to pay for the Apple developer registration, I think it is $99/year. But make sure you do not sell too many of them and get more than $100 000 revenue or next year you have to buy the Pro version (you will have felt a sense of irony in this last bit).
