I want to make 3d games for the iphone and with all this doubt about Unity and Apples new sdk agreement I'm wondering what the best way forward is?
A lot of people recommend opengl es and point me in the direction of the open gl es bible and likewise, the problem is none of this actually talk about setting a game up i.e loading a character, scene , AI etc.
Yet a lot of people are using Open GL es please could someone help me out, I really feel like I'm missing out on something.
Are there any good tutorials/books that cover this?
Thanks,
The Oolong Engine was written and is maintained by professional game developers. It should get you started on some concepts, but programming a game from the nuts and bolts is a big step from using Unity. Good luck.

I have good experience with the iPhone development tools and making apps with window based applications and stuff. I am now trying to make an awesome 3D game, which is an area I have never tried out.
I am very interested in learning about the development of "INFINITY BLADE" and I am very curious to know how it was developed and how they were able to develop it with so much detail.
I had already looked at links like iPhone 3D Engines, but it seems outdated.
Where is a good place to start for learning HIGH Performance 3D games for iPhone / iPad ?
Could you share any tips on the development life cycle for the 3D Games ??
Tools used for making high quality 3D images for the creative side of iPhone Development ? And resources on the creative side ?
Could you share the game development life cycle for a particular app , or perhaps your comments on the development of Infinity Blade ?
This isn't a full answer, but I decided to post it anyways.
Infinity blade was written using unreal engine 3, which recently (or not so recently) got an export to iPhone option. Unreal engine is the same engine used for games such as gears of war. I'm assuming that the actual difficulty of getting high quality graphics to run well on the iPhone was handled by unreal engine. As for making the graphics, I'm sure they hired a (bunch of) 3D artists. You can get the UDK for unreal off of their website, which allows you to start learning with it. The only caveat is the cost of the engine when you actually want to release a game.
I've never actually used it so I can't give too much information on it, but you could try looking at cocos2d's lesser known sibling, cocos3d. That would probably be the most cost effective way to learn how to do some 3d game programming in obj-c.

But if you're looking to bang a game out quickly and learn a good amount about game development, Unity3D might be the best option. They have a few really good hands on tutorials.

I might be wrong, but I think Unity might require the use of C# under mono, in which case I'm not sure if that would be something you're looking for.
Have looked so long for a library specialized in dealing with iPhone Accelerometer but couldn't find anything.
I have made some few sample apps, but none reaches a level of accuracy as in Labyrinth games for example, so any idea about a library for that? Or maybe an open source app?
Would be better if it's integrated in a Physics library
UPDATE: I didn't mention it, but i don't want to use game engines. Specially now, that their future is still unknown. ObjC libraries or tutorials would be better.
I highly recommend looking at tweejump. It's basically an open source version of games like Doodle Jump. It really helped me learn how to use the accelerometer to control an object on the screen.
Although you said you didn't want any game engines, this is powered by the Cocos2D library. However, Cocos2D is written in Objective-C, so there shouldn't be any issue getting anything powered by Cocos2D passed Apple.
Best of luck!
It seems that it may just be easier for you to use a game engine that works with iPhone if you are looking to make a game. Here are 2 engines that export to iPhone GameSalad or Unity 3D
All I want is really absolutely basic 2D drawing stuff e.g. rectangles, circles, paths, curves, béziers and so on. I don't need all the 3D model meshes with all this texturing and lighting. Is there a good learning resource for a fast startup programming just for fun?
I agree with Hetal: Get an OpenGL book.
But if you don't like that advice check this one out on amazon. It might help you start game programming on the iPhone. It also has links to other books that you can also purchase on amazon.

One other option is to of course use google to look for OpenGL ES tutorials such as this one: http://iphonedevelopment.blogspot.com/2009/05/opengl-es-from-ground-up-table-of.html
The Red book for Open GL is a good starting point to learn Open GL. You can get it online. Just google.
Also don’t skip Jeff LaMarche’s Tutorial on OpenGL ES for the iPhone.
What are people using mostly to build iPhone games with? I'm learning iPhone programming. Currently I'm watching all the stanford vidcast, doing the assigments and going through the beginning iphone development apress book. I want to get into building games and want to know if developers are buidling everything with opengl es or are they using pre-existing game engines?
Depends how graphic-intensive the app is.
If it needs a lot of graphics, go with a pre-existing engine.
If not, many use OpenGL ES
I believe most people are simply using Apple's APIs. Other than that, I think cocos2d is pretty popular.
You can find a bunch of suggestions here:

Which technologies/concepts do you suggest I learn before creating an iPhone game?
I used Unity. There's been a lot of great games (even in the top 10) that used it. You don't even need to know objective-C. The code is written in scripting languages using C#, Javascript or boo and then compiled. It is expensive. It will cost you a minimum $600 for an indie license to do iPhone apps. unity3d.com
It's tough to get up to speed writing a game with all the APIs to learn and few good game examples (especially if you are new to Objective-C). I ended up tracking down the old crashlander source, which is notoriously hard to find since Apple pulled it.
There are probably half a dozen iPhone game programming books in the pipeline. Until then, the learning curve is pretty steep.
I'd suggest starting with an OpenGL 2D sprite-based game. Start by learning OpenGL ES, the touch system, then the audio system.
I know Java pretty well. I know now most of the Basics in Objective-C.
I know nothing about Photoshop. I know how to use TurboCAD 10 Professional, so I do have some experience in 3D object modelling. Although not much.
What do I have to learn step-by-step, to come to 3D game Development for iPhone? What Tools do I need? Which Books help out? How long did you learn?
Learning the basic ins-and-outs of OpenGL ES on the iPhone took me about 3 weeks. I post some of my observations on the subject here. The source code to my Molecules iPhone application, which uses OpenGL ES, is available here. Maybe you'll be able to find something useful in that example. However, there's nothing in there that deals with textures, which you'll probably need for your game. Bill Dudney has posted source code for a Wavefront OBJ modeler on the iPhone that may help in that regard. For a good text on OpenGL ES, I'd recommend "Mobile 3D Graphics: with OpenGL ES and M3G".
When it comes to Cocoa development in general, it will take you a little while to get up to speed. For me, it was about 6 months before I felt comfortable with it, although that was in the more complex Mac desktop environment. I post some resources for learning Cocoa here, although that's by no means an exhaustive list.
I agree with diciu, this is a bit much for someone just starting out on the platform. I'd find a simpler application or series of targeted applications (that you may never even release) to help you learn the core concepts before you leap into 3-D game design.
Your goal is very ambitious - I think it's a very hard project to tackle as the first project on the iPhone and you'd be better off starting out with a couple of simple Cocoa touch applications to get a feel for the platform.
For a simulation game I would start with experimenting with some physics engine such as bullet. Bullet is C++ and you can use it from Objective-C++.
For rendering 3D you probably want to use OpenGL ES.
I guess that OpenGL is worth a look.
