Sometimes, usually a couple times a week, when I try to unlock my iPod the sleep or home button don't do anything. So I have to do a hard reset by holding both buttons. This has been happening since 1.1.1 clear up to 5 minutes ago in 1.1.4 (all jailbroken). Has anyone else encountered this? Is this probably just a side affect of jailbreaking, or could it possibly be a hardware issue? Also, when I have the brightness down low to save power, I notice the screen softly flickers slightly from time to time. Mainly noticeable when you're reading something. Thanks.
