Today while on my iPod touch, I got a facebook notification on my lockscreen. Now originally the backlight was off, but the notification turned it on. I double tapped the home button to bring up my mini music player. Well, upon doing this, and the notification still up, the mini player popped up, without the volume slider. A respring did not fix the problem, and any time I double tapped the home buttom, the mini music player popped up, without the volume slider. Now I rebooted my iPod, and all was fine. I just wanted to share this little error. I have an iPod touch 2g on 3.1.3 jailbroken.
