I have a jailbroken iphone 3GS. Today I was using it and it ran out of batteries. So I think to myself, no problem, I can just plug it in. And I do. The computer does not recognize my USB and doesn't make that little sound. The iphone makes that little symbol with the electricity and the plug. I borrow my dad's charger. No luck. Try rebooting my computer. Then I try a hard reset and nothing seems to work. After about 4 hours of googling I realize that maybe I should just buy a new battery. Do you think that would work? Please don't answer if you have no clue. ---------- Also my battery is about 18 months old. Warranty is long gone. iOS 5.
