I bought a factory unlocked WCDMA iPhone 4 at Shanghai Apple Retail Store, and facetime works fine with China Unicom. This month I came to US and bought a T-Mobile sim card. I can make phone calls and do sms, but I just cant use facetime no matter what I do.


BTW, I dont remember how I did it, but I believe I've set my iPhone 4 to recieve and start a facetime call via email instead of sms. I'm not sure if that has been automactically changed when swiching to T-mobile. I can now use facetime on my macbook pro with the same email account, but not with my iPhone. They worked great together while I was in China.


I'm sure my iPhone is running the latest version of iOS.



iPhone 4, iOS 4.3.3
