I've had my 32gig 3gs jailbroken pretty much since day 1 of release, had no issues until today. My battery meter seemed kinda weird as it was 80% then it shut off, and said it was dead, I charged it for a couple of hrs, and it was at 20%, then after a few more, it jumped back up to 100%. Then I left it for a few more hrs, and it was dead again, i've plugged it into the wall and have been charging it for a few hrs, but it just stays on the red battery charging screen.... any ideas?? Thanks!
