I just bought The iPhone Developer's Coocbook by erica sadun. Wondering about writing programs for my jailbroken phone. Is there anything I should know about that is special for developing programs for my iPhone? One thing the book says is that you can't run programs directly on the iPhone until you have entered apple's iphone developer program. I called apple and the guy said if your phone is jailbroken, you can run your own applications. Just wondered if there was anything I need to know about developing programs for my iPhone?
