Answer 1

I'm not sure I understand your question, but you might want to have a look at the UIDevice class. It has a property model which returns a string like "iPhone" or "iPod Touch". You didn't say why you want to know whether a device is new or "old", but if it's about whether multitasking is supported, that's what the multitaskingSupported property of UIDevice is about.

Answer 2

This code returns the device hardware name with numbers that go higher with newer hardware:

char machine[256];
size_t size = 255;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
if (size > 255) { size = 255; }
sysctlbyname("hw.machine", machine, &size, NULL, 0);
