Answer 1

 NSString *str_mainMenu = [[NSBundle mainBundle] pathForResource:@"Unlock" ofType:@"jpg"];
    mainView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageWithContentsOfFile:str_mainMenu]];

Not presently, the only thing that you can do is save the image to the camera roll and give the user instructions on how to change their wallpaper using the new image.
