Hi people. I have been wondering, how can you customize the iPhone Firmware? I know a lot of programming (though I need to get my head around Objective-C soon, heh), and I think I could do it if I at least knew how to. Do I need to know the hexadecimal and binary counting systems?

My apologies if this is in the wrong section, but if anything, just move it to the right place.

Thanks for any help I may receive !
