I put my iPhone in DFU mode, and I went ahead and restored my phone, since I couldn't hear out of the ear of my speaker, I was guessing it was a software problem, after I had done that, it showed me a screen where it told me to plug into my iTunes, I did, and now my iTunes says that it doesn't support my Sim Card since I have T-Mobile as my carrier. I was thinking that taking out my Sim Card then plugging it back in would do the trick, but the problem is, is that my Sim Tray is jammed and I can't get my Sim out. How do I go back to the old screen? I need to have my phone working please.
