Question

While it’s not good practise to find out and use this information in your application, is there a way to find what model of iPhone / iPod / iPad you have. For example: 2G/3GS/4G etc

Answer 1

Try:

char    deviceString[256];
size_t  size = 255;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
if (size > 255) { size = 255; }
sysctlbyname("hw.machine", deviceString, &size, NULL, 0);
if (strcmp(deviceString,"iPhone1,1") == 0) { etc... }  // 2G

1,2 is a 3G,
2,1 is a 3GS,
3,1 is an i4, etc.
