SystemInfo.deviceUniqueIdentifier safe for IOS 5.0 and up?

Since last week, the UDID issue apple had talked about extinguishing since IOS 5 is coming to reality as of April (so I’ve read).

I was checking the documentation concerning the SystemInfo.deviceUniqueIdentifier call, and as it says in the description:
"
Description
A unique device identifier. It is guaranteed to be unique for every device (Read Only).
On iOS devices this does not call into any iOS API.
"
So I’m guessing that by not calling an IOS API we’re safe to use it. I read somewhere that “deviceUniqueIdentifier” Unity uses is made by md5ing the MAC address.

Any input into this would be much appreciated!

Bump.

It is safe if you use Unity 3.5.5 or newer.
iOS: SystemInfo.deviceUniqueIdentifier no longer uses deprecated UIDevice.uniqueIdentifier.
