So, I have an iPhone 4(S maybe) that I'd like to use as an iPod. It doesn't have a SIM card, and the lockscreen button doesn't work (Therefore cannot put into DFU mode using lock and home buttons). It is a freshly restored iPhone and won't work without a SIM card. I'm not sure what iOS it is, either 7.x or 9.x. It should be the most updated version, as it automatically updated when I plugged it into my computer. I have tried the Emergency Call method of getting into the phone without a SIM card, but alas, no lock button. I want to get into the phone, and I have no reservations about jailbreaking or anything that *might* damage the phone. I'll take any help/advice that you guys can give me. *EDIT* I have jailbroken iPhones before so I'm familiar with the process.
