NSBundle* bundle = [NSBundle bundleWithPath:apppath];
NSArray *infostmp = [[bundle infoDictionary] objectForKey:@"CFBundleIconFiles"];
if(infostmp){
     NSString* iconPath = [[NSString alloc] initWithString:[infostmp objectAtIndex:0]];
     UIImage*  icon =[UIImage imageWithContentsOfFile:iconPath];

You can get the NSBundle object only in a jailbreak iOS, in a non-jailbreak iOS device, the code: NSBundle* bundle = [NSBundle bundleWithPath:apppath]; get the bundle is nil. So, you can not get the icon.
