I bought an unlock for my iPhone 4S from a 3rd party unlocking service which looks to be reputable (cellular-medic) and was wondering how I can verify that my phone is indeed unlocked. I don't have access to a T-Mobile SIM that I can insert and try it out. When I synced my phone with iTunes, I never got the Congratulations, your iPhone is unlocked message.
To complete the unlock, do I need to restore? I heard that 4S's don't need to do that.
