Try using following : you will get all the detail informations of the Device...

NSLog(@"uniqueIdentifier: %@", [[UIDevice currentDevice] uniqueIdentifier]);
NSLog(@"name: %@", [[UIDevice currentDevice] name]);
NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);
NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);
NSLog(@"model: %@", [[UIDevice currentDevice] model]);
NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

If above does not work for you then use github project

EDIT :

Whether you are on an iPhone or a iPod Touch:

UIDevice *device = [UIDevice currentDevice];
NSString *systemName = [device systemName];

To detect the version of the OS:

UIDevice *device = [UIDevice currentDevice];
NSString *systemVersion = [device systemVersion];

For Reference: how do I detect whether I have iPhone 2G,3G,3GS
