I had to wipe my iPad yesterday and lost about six months worth of diary entries as a result. For some mysterious reason, it stopped recognizing my passcode. I think it may have been hacked when I connected it to the wireless at work that day, which I’d never done before – even though I’ve never heard of that happening.
I suppose I have learned my lesson and will start backing up documents either to the cloud or to my desktop. I didn’t lose too much, but it hurt.
