Okay, so I have a jailbroken iPhone 3G and it was low on battery so I connected it to my logitech pure-fi speakers. I thought it was turning on and it was going to charge as it always did so I left. When I came back it was off so I turned it on. It turned on fine and then once it turned back on it all of sudden went into the spiral wheel and turned itself off. I thought this weird so I tried to turn it back on (while it was still connected) and again it shut itself off again. So I thought I would take a USB of mine and connect it to my macbook. It did it again! THen I thought well let me restore my phone. It wouldn't come up on iTunes! Funny thing is I am able to use my Iphone while it is not connected to my computer. Sad part is that it only has 10% of battery life left. I don't know what to do! Any help?
