Ok, I was asked how to save dafts in email. It is pretty confusing on

where to find it. Once your in your email, either a plan email or a
photo email, simply hit the “Cancel” button. You’ll then be asked to
either save or not. Your email is then moved to the “Drafts” folder.This is important to know because if you don’t, your letter will be
stuck on your email app or photo app.

This is very, very important for people like me writing blog posts by
directly emailing their posts to a blog. As far as I know, iPhone does
not automatically save a draft of your email. So when writting a long
or important email (or blog), it’s a great idea to save a draft. If
your iPhone freezes, your email won’t be saved as a draft.

Peace, J
