I believe my iPhone is jailbroken
I believe that my iPhone was jailbroken. Because I don't see AT&T 3G on the top left corner. And when I checked my iPhone, there are some default apps that are deletable. And I'm really need you guys to help me and tell me what to do. Because I seriously want to know what is going on here and tried to post in Reddit and other stuffs, but noone answer me. If Apple community doesn't answer me then what should I do? I tried to connect to iTunes to check and this is what I received.
iPhone 5, iOS 10.3.3, null
