How about this code, if new version was released, you will identifier with the last know device

 if ([sDeviceModel isEqual:@"i386"]) return @"Simulator"; //iPhone Simulator

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: <a href="https://github.com/erica/uidevice-extension" rel="nofollow noreferrer">https://github.com/erica/uidevice-extension</a>

<pre><code>#include &lt;sys/types.h&gt;
#include &lt;sys/sysctl.h&gt;

@implementation UIDevice (Hardware)

/*
 Platforms
 iPhone1,1 -&gt; iPhone 1G
 iPhone1,2 -&gt; iPhone 3G 
 iPod1,1 -&gt; iPod touch 1G 
 iPod2,1 -&gt; iPod touch 2G 
*/

- (NSString *) platform
{
 size_t size;
 sysctlbyname("hw.machine", NULL, &amp;size, NULL, 0);
 char *machine = malloc(size);
 sysctlbyname("hw.machine", machine, &amp;size, NULL, 0);
 NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
 free(machine);
 return platform;
}
</code></pre>

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

Detect the specific iPhone/iPod touch model

 可能重复：我正在制作一款利用iPhone (可能还有第二代iPod touch )的点对点蓝牙功能的游戏。然而，为了阻止用户尝试在第一代iPod和iPhone 2G上玩多人游戏，我需要检查特定的设备型号。[UIDevice currentDevice型号]只会告诉我设备是"iPhone“还是"iPod touch”。...
