Hi Andrew,

Patch has been applied, thanks.

> SimManager.ChangePin("pin", "1234", "")
> SimManager.ChangePin("pin", "1234", "1234")

> SimManager.ChangePin("pin", "1234", "")
> SimManager.ChangePin("pin, "", "1234)

> The other problem is that if changing the password succeeds but
> enabling authentiation fails, ChangePin still returns failure

I added LockPin and UnlockPin methods to take care of these two cases.
