I have photos in my iPhone that were added using iTunes sync with a Photos library. I do not see a way to delete them (no trash can icon) and when I tap "Edit" while viewing them I get the following message:
This photo is not editable Do you want to duplicate it and edit a copy?
I understand that I can make a copy and edit that, but then the original will still appear on my phone and there is no way to delete it.
How can I edit these photos so that only the edited version appears on my phone?
