I can say for sure that it has been removed from Italian App Store.
Are you sure? Any experience? (i.e. someone who did JB -----> Restore -----> Apple -------> NO PROBLEM ?). What if they have some way to notice it after all? I hope you're right.....
As for me, the fact is also that I don't need those functions that bad.....
I have done so with my iPod Touch-I restored Apple firmware when I needed to take it in-they never said a word.
