iphone 4s is locked
I've brought a Iphone 4S, in Apple Store, Regent Street Flagship store, London, UK.
And I bring it back to China to use, but when I insert my Chinese SIM Card, which indicate the phone is not activated. (UK SIM card is working).
So could you pls help to check and settle it? Is it be locked by UK or by any carrier?
iPhone 4S, iOS 5.0.1
