I am running the current firmware (3.1.2) and I Jailbroke it using Blackra1n. Everything was good for awhile and then it suddenly stopped lighting up. I have the Brightness setting maxed and it makes no difference. I restored the current firmware (unjailbreaking it) and that made no difference. I read somewhere that if you hold down the menu and power button to reset it, it would come back. I did this once and the light came back on before I reset it and then when it reset, it was not working again. I've only had the Ipod for 6 months. Any ideas why the light sensor is not working or methods to try and get it going again? Also, there is no physical damage to the area where it is.
