My phone was jailbroken, and I had to remove it, because I messed up my network settings, and couldn't fix it. I backed my phone up, reset it, and restored my backup (my jailbreak is gone now). HOWEVER, when I connect to LTE, nothing loads. Can't even send texts, etc. So, if I brought my phone into the apple store and showed them that my phone loads on 4G but not on LTE (and I don't tell them I jailbroke) would they give me a new phone? Would they be able to tell I was jailbroken, or will they assume my phone is defective?
