IPhone :: No Facetime Option Or Settings For 4s IOS 5.1

An iphone 4s without facetime! I bought an iphone 4s from a retailer, i found out that the iphone 4s was originally came from UAE with a carrier etisalat. so called etisalat and i was informed by the Representive that the facetime was really banned in the country and was remove with the IOS 5.0.1 as defualt but they also verified that the iphone is factory unlocked, then i was advised that all i need to do is to restore the my iphone and i will have my facetime back since it is not banned in this country (Hongkong). so I tried to update my iPhone to iOS 5.1 however facetime setting still missing! check restriction no facetime, check phone setting and theres no facetime activation option. tried to factory reset the phone and choose country and region facetime still not available. So what i did is called apple and i talk to apple care Representative a very rude Agent and loves to Interupt his customers. i was told that whenever i update or restore my iPhone it contact the UAE apple server. and it doesn't make any sense im not in UAE im in Honghong. So i ask the rep. what can we do to make itunes contact hongkong or singapore apple server instead. Apple cannot give me a direct answer.So ask him if it something to with IMEI , Model or Serial Number, and they cannot give a direct answer again..... Come on Apple whats the sense of you releasing a factory Unlock if theres a Restrictions i Know that it the Law of UAE but you should do something About based on the location of the Customer....
