I've been around the jailbreak seen a while and have had my share of tweaks that do things SO close to what I want, but not exactly what I'm looking for. So, I've decided to make my own. However I've run into a slight problem... How do I access an iOS System file from inside my app? I'm looking to load a plist file from the system, back it up, change it, and put it back.

I only really need help on accessing it. I'm sure I'll be able to piece together the rest.

Is there anyone that would be willing to give me a hand? I've written a couple of small apps that my family uses on their iPhones (flashlight, podcast feed player, etc) so I know my basic way around code. I'm using xcode. Don't know if that matters for system access..

We can either chat here, via e-mail, or private message.

Thank in advance
