yesterday i cleaned my headphone jack whit a pipe cleaner but since then my ipod does strange things. volume down wont work trough the volume rocker, volume up will lock my device. when i lock my device it will display the power off slider. every 1 min the device will show my lock screen but i don't did anything. I think i bend something in the headphone jack but i'm not sure. I already tried to restart my device but that didn't work.
