Answer 2

There are ways to detect whether your app is running on a jailbreaked device or whether your app has been modified (aka cracked). Take a look here and here for example.

From my point of view all you are getting by using these methods is a waste of time. Maybe you can make it harder for potential crackers and keep away the script kiddies. But you won't get that far that no talented cracker on earth would be unable to crack your app. Even one single cracker on earth who's able and motivated to crack your app is enough to upload it to hundred's of sites.

If really big companies fail at protecting their apps I really doubt that you will achieve it... so: wasted time which should be better spend on improving your app.
