Siri might not be able to directly update your Facebook status or send a tweet, but there’s a workaround that can be handy. These social networking services can be updated via text message, and Siri is great at sending text messages. All you have to do is configure your accounts to accept updates from a text.
Facebook

Activate the feature on Facebook by texting “Hello” to 32665. (Find codes for more countries and other details from Facebook help.) You will receive a text message with a link. Tap the link to confirm and add the code you receive to the Contact list. If you name this contact Facebook you can tell Siri to send a text to Facebook.
Google+

In Google+ navigate to the Settings and choose Set delivery preferences. Add your iPhone 4S phone number (choose don’t notify me or else you will receive incoming messages by text). You’ll receive a confirmation text message with a verification code. After you’re verified, add a new entry to your Contacts for Google Plus with the number 33669. Tell Siri to text Google Plus and your circles will see the updates. Find more details about Google+ and text messages from Google.
Twitter

Sending updates to Twitter is similar, just text “START” to 40404. (Find codes for more countries from Twitter help.) When you receive a text from Twitter, send back your username first, then your password. When you receive the code, add this number to your Contacts under Twitter. Tell Siri to send a text to Twitter and it will become a tweet.

Step 1. For starters, you must create a new list in the Reminders app. To do this, tap the list editor icon in the top left hand corner of the main screen (looks like three lines). Then tap the edit button, and select the Create New List option.

Step 2. Name the list whatever you want. For the purpose of this tutorial, I named the list ‘Grocery.’ Then tap the Done button in the top right hand corner of the screen.

Step 3. Now that the list is created, exit out of the Reminders app. Activate Siri and say, “add [milk] to the Grocery list.” Siri then confirms that you’d like to add the item to the list, and then does so. You can open up Reminders to view the list at anytime.

This is really handy: start a list called “Grocery” in the “Reminders” app, and then share it with your shopping partner’s iCloud account on iCloud.com.

Boom: Shared grocery list, voice controlled. When you get the the grocery store, just say “Show me my grocery list” and Siri will pull it up for you.

INSTRUCTIONS

1. Get iOS 5 installed on both phones, and set up iCloud with Reminders syncing turned ON.
2. On one of the phones, tap the Lists icon in the upper left corner of the Reminders app. Tap “Edit” in the upper right corner.
3. Add a new list called “Grocery” (if you’re using Siri, it’s better that it’s “Grocery” singular, and not “Groceries” plural, for better sentence flow).
4. Log in to the iCloud.com account for this phone.
5. Go to Calendar.
6. Click the “share” button (looks like an RSS icon) next to the “Grocery” list you created.
7. Enter the iCloud ID of the person you want to share it with.
8. Have them confirm the e-mail they get.

Many people don’t know this but many app developers enable their apps to be opened from other apps or the web using whats called iPhone URL schemes. For example, go into safari and type in the URL box fb:// and hit return. It opens the Facebook app on the iPhone. Or try twitter:// or IMDB:// and you will see it open those apps on your phone directly. I thought this could be potentially useful using Siri in the following way.

1) Create a Contact in your address book and call it Shortcuts (I called it applications, apps is a reserved siri word).

2) Create multiple text fields (home page fields) with these Url schemes. Then you can tell Siri - “Show Shortcuts” and it will pull up that contact sheet and list all the URL shortcuts which can be clicked on.

Now, doing this just to open an App is probably not useful, but the iPhone URL schemes also support advanced functions in apps which I think could save time. For example, if your enter into a text field: fb://birthdays it will take you directly to the Facebook birthdays page within your Facebook app. Or try fb://albums and you go right to facebook photo albums. Unfortunately, these enhanced URL schemes are hard to find but i figured if people knew about them, the experimenting can begin.

Here is a link to a partial list of known iPhone URL Schemes: http://wiki.akosma.com/IPhone_URL_Schemes

caps on … caps off	to capitalize a section of text For example, saying: caps on twenty five ways to eat bacon caps off produces the text: 25 Ways to Eat Bacon
all caps	to make the next word all uppercase For example, saying: I am hungry feed me all caps now please produces the text: I am hungry feed me NOW please
all caps on … all caps off	to make part of what you say uppercase For example, saying: I am hungry all caps on feed me now all caps off please produces the text: I am hungry FEED ME NOW please
no caps	to make the next word lowercase For example, saying: I like no caps Mike produces the text: I like mike
no caps on … no caps off	to make sure part of what you say is all lowercase For example, saying: Our friends no caps on Steve and Tina no caps off live in California produces the text: Our friends steve and tina live in California
