iPhone 4 is working but screen is black?
Yesterday I dropped my phone, and it was working fine when I picked it up to check it, but a few minutes later the screen went black. I know it was still working, because I was still receiving phone calls, texts, and mail. I even took a picture with it.
I've tried holding the home and lock button. I also tried holding the lock button while constantly pressing the home button, but I think the problem with this is that my home button barely worked before the drop. I've tried to reset it and put it in DFU mode, but nothing is working. :( Note that I can't take it to the shop because it's jailbroken.
