I know that Facebook and Twitter open source the in-built libraries for iOS, but i wonder if someone goes further and open sources the whole app's codebase.<p>It is obvious that there is some security concern involved, considering the exposure of private API's and etc.
You can't hide API's :-)<p>I took apart the Disney Parks App as I was frustrated at the fact the full information therein was only available if you're physically inside the park.<p>Firstly, I used an American friends App-Store account to download the app, as it was not on the UK App-Store and you need an US credit card to set up a US account (Please correct me if I am wrong here.)<p>Next I used Fake Location, a €3 app from the Cydia store on my jailbroken iPhone, so I could convince the app I was 4500 miles away in Florida in the sun.<p>Finally, I used "mitmproxy" on my Mac, to proxy the web access the Disney app was making to the server, and noted the URL's and over time worked out the structure of the API and it's JSON replies.<p>Hope this is of use :-)
