I am new to Unity Game Engine and community for iPhone. I went through the game tutorials and I appreciate if you can please point me to the documentation for iPhone and Game Tutorials where I can develop some solid foundation and start developing some small basic games.
The iphone documentation can found in your installation. its not offered anywhere else.
As for tutorials: the majority that you need and can learn about Unity is the same on Unity and Unity iPhone.
For the iphone specific aspects, I recommend to check out the Unity iPhone Examples in the resource section on the website
And FWIW, when we release Unity iPhone 1.1 we will release a new iPhone specific tutorial. That tutorial will walk you through building components found in Penelope which you can download for free as an app in the AppStore today:
Note: an update to the AppStore build is pending as well, we had to fix some minor issues.
