Saw an article that said after installing an iOS update, nude photos thought deleted years ago are reappearing in photo album. You might think no big deal, but this was reportedly happening on devices thought to be factory reset before selling or returning them, so other people now have your nudes. Seems like the act of deleting didn't overwrite the memory space. I don't think I took naughty pics or vids on my iPod that I had to unexpectedly hand over for a repair replacement since the Apple Store didn't give me any indication that's what I had to do so on the spot had to decide to reset the iPod before surrendering it. I should have taken some super long hi res video with it first just in case to use up memory to overwrite stuff.
