So yesterday at around 7pm my iPhone 4 died, and wouldn't charge. I've tried hard booting it (holding the home button and sleep/wake button at the same time), plugging it in for a few hours, and just plain old trying to turn it on. When it first died yesterday, the little red battery symbol showed up saying to connect it to a power source. Now, today, it doesn't show anything. Just a pure black screen, no matter what I do. I haven't called in to apple or brought it in, because I just simply do not have the money for that.
Is my phone a goner? Or is there anything else I can do? (Can't plug into iTunes as my computer is broken).
Any help welcome! It has All of my information on it so I'm desperate!
