iPhone 3GS battery doesn't get charged once it went completely low and turned off. There low battery symbol appeared on screen and when it seems to be charging white apple logo comes up and nothing happen again. After apple logo it again plunged into low battery symbol. And this cycle is continue since three days. I tried to charge many hours, over night, more than 14 hours but nothing worked. I also tried to jailbreak it again so that I won't loss my data but it didn't work as well. In jailbreaking process when it gets restart it stops again on apple logo. Only option seems to me is restore it but I am afraid of loosing my data, my videos, my pix in software called "downloads" and my favourite guys in grindr. Before performing that operation I wanna ask some expert's opinion here.... What is other option available to me ?!
