I have an ipod 2g that I jailbroke with the jailbreakme.com website and it is running out of charge without me even touching it. I have woken up each day for the past 2 days since I did it with my ipod dead. I dont have any apps running in the background that I know of. I also only have apps from cydia which I also had when i jailbroke firmware 3.1.2.

Anyone know what else I should look for to find the culprit?
