@CreamPuff apparently so, though to be fair it was my wife that dropped it & not me.
She did feel really bad about it, though admitted had I done it she would be been very upset / angry with me
(Apologies I don't have names to respond to, Tapatalk just showing me the screen for typing, not the posts)
We looked at the videos about doing the glass replacement ourselves and decided that it was a little too tricky and too easy to mess up; plus we lacked a heat gun. So the missus decided just to go ahead and get it replaced for the princely sum of 229€. Nicely they simply replaced the whole phone rather than swapping out the screen unit.
Phone is not restored yet as my backup is against iOS 7 beta and I can't get the beta yet as Apple's Developer website is down since last Thursday. So for now it's just a basic phone & a couple of essential apps.
