Should I be concerned that my iPhone 4S doesn't show the typical "congratulations, your iPhone has been unlocked" message? I placed an order for a factory unlocked iPhone from apple store and it just arrived today. I was using BB before, so I called up AT&T, told them to switch my grandfathered data plan to an iPhone plan and everything went smoothly. I insert my ATT SIM card and do a restore on the iPhone, but I didn't see the "congrats" message. I had an unlocked iPhone 4 which I bought from Canada and it showed me the congrats message whenever I do a restore. Sooo.... is there any other way you can tell it's unlocked? Other than buying a different SIM card of course.
