Upon returning home this afternoon. I powered up my laptop to continue some music downloads i have going (all legal don't worry). and noticed my ipod turn on as normal (since it is plugged in) Since it is jailbroken I watched it go through what seemed to be a normal verbose boot (no apple logo, script running down the page). then when it finished booting, it showed a yellow screen. nothing was responsive, so I unplugged it and manually shut it down (top button and home for 10 seconds) the yellow screen went. Ive never seen or heard of a yellow screen issue before. so anyone have any idea what it could be. I've had it happen one more time today but seems to have gone now. Any ideas??? Jailbroken on iOS4, with multitasking and background wallpaper enabled.
