Jailbroken iPhone 3gs will not turn on
This morning I went to use my iPhone 3gs after it had been charging all night, and showed 100% battery life. While I was poking around the phone froze and I was unable to do anything on it. I held down the home and sleep buttons at the same time for about 30 seconds and the phone rebooted. Since then, it has stayed on the "apple" logo screen, all day. I have tried to reboot it the same way as before several times, and it turns off, and reboots as if it is trying to start, but nothing happens. My phone is jailbroken using greenpoison about 6 months ago, and I have never had any problems with it. Once the apple screen comes up, it changes to the "apple skull" usually shown with jailbroken phones. My battery is now dead and even after plugging into the wall unit, it still does the same thing as before and will not turn on.
My original plan was to plug it into the computer and see if I could simply restore it, but when I plug it into itunes it won't recognize that any devices are plugged in. I plugged in my ipod, and ipad, and itunes recognized them immediately, and I heard the classic sound indicating a USB device was plugged in on my computer. When I try to plug my iPhone in it does nothing. The battery however was dead, and when i plugged it into the computer it showed the power sign, as if it was charging from being dead. The only thing I can think of is that since technically the iphone isnt ON, itunes wont pick it up.
I know this is a LOT of information, but hopefully some people kept up with me
ANY help is so greatly appreciated, I feel naked without my phone
