How can it be that the topbar shows the network the iPhone is on and not the actual carrier, listed under "Line"? In my case here, "BiBoB" is my carrier, while "Sonofon" is the network they're using. There is a carrier called "Sonofon" also, but that's not my carrier, it's only their network my carrier is using. Is it possible to change this? Possibly via jailbreaking? I know about MIM, but it would be nice if it would show the "Line" automatically. Thank you.
