What you mean by "Open Source cell phone code"? You looking just for some code examples to learn o you want to participate in open source development?

First step would be, find if your Brand Company allows open development for the model.

I own a Samsung instinct and I know Sprint offers emulator, api's and sample code for testing.

Otherwise you might have to buy a development package including a special version of the phone, software, and api's.

@PhiberOptik nope have look here for starting point in Java mobile development http://www.daniweb.com/forums/post646446-14.html
