2G Ipod 3.1 Firmware The thing that measures how much battery life is left in my ipod is not working properly. Its telling me that is almost fully charged when its actually about to die. It gives me no warning so it will shut off when i'm in the middle of something. I have left it charging all night and i have used it until it died so the battery is already having problems. But this has never happened before. Is there a way to fix this? Should i just fix it myself because my warranty is up?
