Alright, here goes: As paranoid as I am, I am very confident with hacking and modding things such as the iPhone or video game systems, so a problem such as a low level of courage won't be an issue. Trust me on that. My question is this: Is there a way that I could jailbreak my iPhone 3g, install 1 app, and then unjailbreak it, get rid of the Installer application, but keep the 1 custom (homebrew, I don't really know what we call it here) application that I jailbroke it for? Thanks in advance for all the help.
