If you use Twitter on a regular basis, you've probably got your favorite Twitter apps but what about when you don't have the time or the hands? Next time you think of something particularly interesting or witty you'd like to share quickly, let Siri help you!
Before you can tweet using Siri, you'll need to make sure that you are signed into Twitter via the Settings app. If you aren't already, make sure you sign into your Twitter account before proceeding.
