Note app keeps on crashing whenever I try to make a new note or deleting a note. I tried everything (resetting the settings, holding down the power button and home button at the same time until apple logo appears etc etc). Even when I try to sync my notes in itunes, the itouch shuts down itself, disconnecting from the computer. Please help, there are a lot of important stuff in my notes and I wasn't able to sync and back them up
