EDIT: Vibrator seems to stopped working, vibrate on touch doesn't work anymore, and it doesn't even vibrate in service menu on vibrator.

Also when I lock my screen I can't come out of it again, help?

EDIT#2:It seems the phone stopped working with vibrate/lock as soon as i put the perm root files on it from the miro thread, which apparently works for every phone.I will stay at .16 as I don't need an sms counter.Thanks for your trouble people.
