How can I dual boot my iphone or ipad to run a very simple custom os?

Question

I am an experienced C/C++ programmer and have worked with assembly and many other programing language and I want to start a project as a learning process. I want to try and run a simple custom os on the iphone or ipad. What knowledge would I need to do this, and how does the iphone or ipad bootloader load the os and how could I modify it to load a custom os?

Im not really sure what to ask here so I really just need to get as much information as possible so I could ask some more informed questions to get my project started

Thanks

Answer 1

The first objective is to find a way to launch custom code on the iphone/ipad. Unfortunately for you this is virtually impossible. Although some jailbreaks exist for the iphone, the flaws that allowed people to put their own custom code onto the phone have mostly been closed. It's possible to do it still but it creates a tethered jailbreak, which means upon resetting your device, you will lose any custom code you managed to get onto the phone/ipad.

I would suggest finding a different device to use for your experimentation.

Take a look at the iphonelinux project. It's in a very early stage and uses the same exploits that allow jailbreaking.
