Smart quotes are a great feature of iOS Mail

First open the Mail app, and then open any email with text in the body to try this out
Tap and hold on a text block to summon the traditional Copy/Paste/etc popup, and use the selection sliders to select the text to quote
Tap on the "Reply" button (little arrow), then tap "Reply"
The reply will contain only the selected text in quotes
