Detect the specific iPhone/iPod touch model

Possible Duplicate: 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.
