I am a professional software developer focusing mostly on iOS. I've jailbroken my phone and am pretty excited about the whole thing. But I am having trouble finding value in the jailbreak community aside from: releasing apps that Apple doesn't need to approve, and the downloading and installing of themes. What exactly can I do as a developer in the jailbreak community? I'm not interested in cracking and stealing apps/anything else. But I think it would be fun to make hacks. Anyone know of some good resources on learning how to make jailbreak hacks? For instance, things like Infiniboard - or what if I completely wanted to re-program how the iOS UI works/looks like? I've got the skills, but am not sure where to start here. Suggestions?
