The iPhone 4S ships with a Notes app. You can use Siri to start a new note, add words to an existing note, and pull up notes based on keywords. The Notes app isn't a full-blown word processor. For example, there aren't multiple font styles or sizes to choose from (only one for each, in fact), but it's an ideal tool to flesh out ideas and make lists and such. And with iCloud, Apple’s handy way of synchronizing all of your digital info and media over the Internet (between supported devices), all your notes can be synched with all your devices, too.
Creating a new note
Here's a look at starting a new note:
Press and hold the Home button.
You'll hear the familiar tone, which is your cue to begin talking.
Instruct Siri to create a new note for you.
You can say something like, "Note that I spent $50 on the fantasy football pool," "Create a note called 'Buy these books' for mom," or "Take a note: Pick up that new Xbox 360 game for Steve."
Siri opens up the Notes app, begins a new note with the name you've given it, and then shows you the note it just created for you. The first few words of your spoken note become the name for the note, but you can change that if you like.
You won’t get a chance to accept or cancel the note Siri creates for you. If you don't want to keep the note, you'll need to manually open up the Notes app and remove it. You can't delete notes using Siri.
Take note that you can ask Siri to create a note in different ways, such as saying, "Make a note about this," "Take a note about that," or just "Note that I did this and that."
Adding to an existing note
Let's say you already created a note on your iPhone 4S and you want to add more to it. You can do this very easily with Siri's help. All you need to know is what the note is called, and you can add more text using your voice:
Press and hold the Home button.
You'll know it's time to talk after you hear the familiar chime.
Tell Siri something like, "Add cereal to Shopping List note."
Remember, the note you're adding the extra words to must already be in your Notes app. Remember, when you start a new note, the first few words will be the title for the note.
Look at the screen to see the note and and, assuming it's all good, you can put the phone away.
(Optional) If you need to edit the entry, tap the message, and the Notes app opens.
As you can see, Siri won't always capitalize proper nouns ("jobs" should be capitalized in "Steve Jobs"), so you can manually change this by tapping the screen.
Finding notes
Your voice-activated personal assistant can also be used to find existing notes on your iPhone 4S. Instead of manually scrolling through all your notes, you can ask Siri to show you all relevant notes by saying a keyword or all your notes, if you prefer:
Press and hold the Home button.
You can begin talking after you hear the short chime.
Either ask Siri to display all your notes or ask her to look for one in particular.
Tell Siri, "Show me all my notes," and you'll see a list of them, from newest to oldest. Tap a note to open one up.
Alternatively, ask Siri to look for a particular note by telling her something along the lines of, "Show me 'book' notes," which will have her call up all notes containing the word "book."
