App bundle protection - signed bundle *may* be modified
Maybe you all know that .app bundle is easily accessible for reading via such tools like iExplorer (surpirise for those who thought only iTunes File Sharing allows to access data on iPhone). Maybe you've also read iOS Programming Guide, section entitled 'Installing App-Specific Data Files as First Launch'. Related paragraph estates:
 
"... Because iOs apps are code signed, modifying files inside your bundle invalidates your app's signature and prevents your app from launching in the future. ..."
 
That's obivously false, at least to some point.
 
 
I've tried to modify several files within SEVERAL free third-party apps purchased from AppStore and sucessfully modified content of several files. Voala, app launched without any problem. The thing is, that I've used iExplorer mentioned above, no hacking, cracking, jail-breaking. Just a development-enabled device, and published, reviewed apps.
 
What should I do?
