I bought an iPhone 5 off of craigslist (used it for about 2 months) and in June my charger broke in which I let my phone's battery drain. ATM I was using it as an iPod, so I didn't really bother to get a hold of another charger until a month later. I've used two different chargers, tried plugging them into my computer and laptop, tried different outlets, clean my charging point, and I have tried holding down the lock and home button for seconds - even minutes. I have been meaning to bring it in the Apple store, but the thing is I don't know if the warranty still applies since I bought it off of someone else and I have jailbroken the phone. I heard that Apple will not give me a replacement if they find jailbroken software on my phone so am I just screwed? I do not know the actual problem to my phone. It could be my home button not working, my lock screen button not working, bad charging port, or bad battery. I'm worried that if I bring my phone in a repair store (none in which are near me) they could charge me whatever they wanted if I said I was clueless on the issue. Does anyone have any solutions?
