Determine device (iPhone, iPod Touch) with iOS

I am making a game that utilizes the peer-to-peer bluetooth capabilities of the iPhone (and probably the iPod touch 2nd generation). However, to stop the users from trying to play a multiplayer on an iPod 1st gen and iPhone 2G I need to check for the specific device model.

[[UIDevice currentDevice] model] will only tell me if the device is an "iPhone" or an "iPod touch". Is there a way to check for the specific device model, like: "iPhone 3GS", "iPod touch 1st generation" or something.

EDIT:

There is a category to UIDevice (I think it's created by Erica Sadun, I don't take credit for it) that uses the following code to get the specific device model. You can find the whole category here along with other useful stuff: https://github.com/erica/uidevice-extension

#include <sys/types.h> #include <sys/sysctl.h>  @implementation UIDevice (Hardware)  /*  Platforms  iPhone1,1 -> iPhone 1G  iPhone1,2 -> iPhone 3G   iPod1,1   -> iPod touch 1G   iPod2,1   -> iPod touch 2G  */  - (NSString *) platform {   size_t size;   sysctlbyname("hw.machine", NULL, &size, NULL, 0);   char *machine = malloc(size);     sysctlbyname("hw.machine", machine, &size, NULL, 0);     NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];   free(machine);   return platform; } 

This works and apps using this have been lately approved in the AppStore.

You can get the device model number using uname from sys/utsname.h. For example:

#import <sys/utsname.h>  NSString* machineName() {     struct utsname systemInfo;     uname(&systemInfo);      return [NSString stringWithCString:systemInfo.machine                               encoding:NSUTF8StringEncoding]; } 

The result should be:

 @"i386"      on the simulator @"iPod1,1"   on iPod Touch @"iPod2,1"   on iPod Touch Second Generation @"iPod3,1"   on iPod Touch Third Generation @"iPod4,1"   on iPod Touch Fourth Generation @"iPhone1,1" on iPhone @"iPhone1,2" on iPhone 3G @"iPhone2,1" on iPhone 3GS @"iPad1,1"   on iPad @"iPad2,1"   on iPad 2 @"iPad3,1"   on iPad 3 (aka new iPad) @"iPhone3,1" on iPhone 4 @"iPhone4,1" on iPhone 4S @"iPhone5,1" on iPhone 5 @"iPhone5,2" on iPhone 5

Most complete UIDevice (Hardware) category probably is http://github.com/erica/uidevice-extension/ (by Erica Sadun):

[[UIDevice currentDevice] platformType]   // ex: UIDevice4GiPhone [[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"
