I have an app that I want to edit. I didn't make the app, but downloaded it from Cydia, then SSHed it off of my iPod to my MacBook. (I took the entire .app folder from the Touch.) I want to change a few things in the app that I don't like. Is there a way to open it in Xcode so that I can make the changes? Also, just so it's not an issue, this is for my personal use only. I want to use it as a learning experience, as well as to "perfect" an app. How can I open it?
