Sign something

It’s always a pain when someone emails you a document that you have to sign. You end up printing it out, signing it, and then scanning it back to yourself. Your iPhone has a hidden feature that will keep you from hitting the print button. Download the PDF attached to your email, click the pen icon in the top right corner, and sign away. Once you’re finished, click Done in the top left corner, and your phone will give you the option to reply to the email with the signed attachment or to create a new email. You can also share signed documents between your Apple devices if you learn how to use AirDrop—it can really come in handy in a pinch.
