Determine device (iPhone, iPod Touch) with iOS

Question

Is there a way to determine the device running an application. I want to distinguish between iPhone and iPod Touch, if possible.

Answer 1

- (BOOL)deviceiPhoneOriPod
  {
    NSString *deviceType = [UIDevice currentDevice].model;
    if([deviceType rangeOfString:@"iPhone"].location!=NSNotFound)
      return YES;
    else
      return NO;
  }
