I have damaged the screen on my iPhone 5, at first it was only cracked but now it is completely black and won't recognise touches etc. The phone is being replaced in a couple of days but I need to back it up and wipe it first. I urgently need photos off the device. When I plug into my Mac or PC it says it can't access the phone because it is locked with a passcode. Is there any way to get around this? Also would I still be able to wipe it without screen access? Thank you.
