iOS Looking for 3D SDK or API for making 3D Games

I'm looking to make a game with similar graphical characteristics as the game "Edge" on the AppStore. In essence, it needs some of the following:

• Geometric shapes with the ability of rotating, pitching, yawing
• Camera that views down on the world and user can manipulate
• Ability to use Blender to import models, environments

The only thing I've seen close to this has been SIO2 - Free Open Source 3D Game Engine. Is there anything better and actually free? This one requires a $49.99 license fee to eliminate their splash screen and any notion of using their API.

I'm fairly new into iPhone Programming but have been programming for awhile already. I already have used Ogre/Blender to create a simple RTS/Tower Defense game for Linux/Windows so I already have some experience making some games.

And using straight up OpenGL is already out of the question?

No. Let me rephrase my question a little better...

What's the best approach to making a 3D game?

If OpenGL ES is a suitable approach, I'll consider it. Does it support importing of Blender models? I've used OpenGL for course work purposes.

iPhone is a fully supported platform on Ogre 1.7. Any particular reason not to use Ogre again?

As far as I remember, Ogre is a graphics and not a game engine (About Ogre). I'd consider using Ogre if there isn't a more suitable engine.

Right now I'm just trying to find out the options I have. I haven't ruled anything out yet. I just want to know what would be my best option before I begin.

Unity Store places support for iPhone at $300.

@chown33, Thanks but I've been doing my research and know how to use Google. I am just looking for some feedback and thought this would be an adequate place to ask.

I also looked into cocos2d, but saw it was mainly for 2d games.

I've heard good things about Unity3D, most of the top games in the iPhone store were made using it. It's also the program that my college uses in its game development course.

Hmm...I'll look into it but the entry price point is a little steep. ~$400 I think? I might just stick to OpenGL ES.
