An article in Emirates Today says that "Computer and music giant Apple has said it is powerless to prevent the unauthorised sale of its revolutionary iPhone in the UAE." The article continues, a spokesperson for Apple Europe says they are "aware of imported sales of the iPhone in countries other than the US but did not have plans to stop it."
It should be pointed out that any iPhone sold in the UAE is unofficial (gray market) and there is no service and support available. Since it has to be unlocked to be used as a phone here, the unlocking will void the warranty, Apple has confirmed.
