Update for iOS 7 and prior:

+ (NSString *)uniqueDeviceIdentifier
{
    NSString *device_id = nil;

    if ([[self deviceModel] isEqualToString:@"Simulator iOS"]) {
        // static id for simulator
        device_id = @"== your random id ==";
    }
    else if (CurrentIOSVersion >= 6.f) {
        // iOS 6 and later
        device_id = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    }
    else {
        // iOS 5 and prior
        SEL udidSelector = NSSelectorFromString(@"uniqueIdentifier");
        if ([[UIDevice currentDevice] respondsToSelector:udidSelector]) {
            device_id = [[UIDevice currentDevice] performSelector:udidSelector];
        }
    }
    NSLog(@">>>>>> device_id: %@", device_id);
    return device_id;
}

Device model you can receive through:

+ (NSString*)deviceModel
{
    static NSString *device_model = nil;

    if (device_model != nil)
        return device_model;

    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *str = @(systemInfo.machine);

    return device_model;
}
