I have searched up custom firmware, and it seems like there is some work on it, but does it require a jailbreak, or just some hacking around? I know you can flash with iTunes so I don't see an issue if I could write my own firm-flash tool, as long as it's signed.
What are your inputs on this, and has anyone ever modified their firmware and what did they do?
