ios - iPhone/iPad unique identifier BESIDES UUID/UDID?

Question

The project I am on is requesting two (or even three) unique identifiers from the iPhone or iPad. I know, I know... the UDID should be enough but we are trying to see if there are any other unique identifiers that we can use.

I can get the IMEI, serial number, MAC Address, etc. from the phone using the IOKit.framework but apparently this is frowned upon by Apple and any app using this framework will be rejected.

Does anyone have any other ideas, or identifiers that I am missing that could be used?

Thanks!

This question is old however a new unique, vendor based, identifier has now been added to replace the deprecated UUID in iOS 6.

The [UIDevice identifierForVendor] should now be used instead of [UIDevice uniqueIdentifier] which is now deprecated as of iOS 5.0

Example usage:

NSUUID *uuid = [[UIDevice currentDevice] identifierForVendor];
NSString *uuidString = [uuid UUIDString];
