I received my iPhone 5 this week and was sent model number ME486LL/A. My plan includes unlimited nationwide 4G data, but the phone is running 3G. I do not have the option to enable 4G via Settings>General>Cellular. 3G is the only option available. Can you tell me how to activate the 4G option?
I live in Cleveland, Ohio where T-Mobile's 4G coverage map says that I should get 4G coverage with no problem.
