Black screen, broken power button, nightmare.
I jailbroke my iPhone 4 with redsn0w earlier today. It was running 6.1.3 and I used redsn0w to jailbreak it with 6.0 firmware. I had no service so spent the past 2 hours trying to find why until I tried a method around an hour ago and it reset my iPhone back to the whole new phone setup process. It then went on to say that my sim card was now not the original one and was unsuitable for my phone and carrier so I turned on my laptop and loaded iTunes where I was confronted by a screen saying sim card unsuitable or unsupported or something. I then tried to put my phone into recovery mode and it is now just a black screen. I can't put it in dfu mode because my power button is broken and no programs will recognize it when plugged in (it won't even charge) so I cannot use my custom dfu ipsw. Please please help me, I cannot afford to replace this phone. Thank you so much in advance.
