I wrote about an alternative here that may be an option for a unique identifier: Determine MAC Address not that the UDID is deprecated.

Unfortunately it is deprecated in iOS5.

Is there a way to retrieve the model type, such as 3G, 3GS and 4? I mainly need to know if the device is a 3 or 4 (G or GS isn’t necessary, but would be useful).

you can get the device model, like iPhone2,1 by using sysctlbyname(), Erica Sadun had a writeup about this at http://arstechnica.com/apple/guides/2009/03/iphone-dev-determining-your-platform.ars

the platform method below will give you @”iPhone2,1″ or whatever the device is

- (NSString *) getSysInfoByName:(char *)typeSpecifier
{
size_t size;
sysctlbyname(typeSpecifier, NULL, &size, NULL, 0);
char *answer = malloc(size);
sysctlbyname(typeSpecifier, answer, &size, NULL, 0);
NSString *results = [NSString stringWithCString:answer encoding: NSUTF8StringEncoding];
free(answer);
return results;
}

- (NSString *) platform
{
return [self getSysInfoByName:"hw.machine"];
}
