I have an iPhone 5S jail broken on 7.1.1. My carrier is T-Mobile. How can I switch networks from LTE to 4G or from 4G to 3G or from 3G to EDGE? I know there's this thing in the cellular settings that says Enable LTE but I don't want 4G or LTE. I want 3G or EDGE. If LTE isn't available, I connect to 4G. If 4G isn't available, I connect to Edge. Is there like an app where you can install from cydia or the AppStore that changes your data networks?
