Hi, it just occurred to me that if you want to quickly tweet from your iPhone 4S using Siri, you can do it without any sort of hack. This requires that you have an iPhone 4S of course, a Twitter account, and a texting plan with your carrier.
1. Sign into Twitter and setup the texting service. When this is done, you send a text to 40404 with your tweet. There are several other things you can do, but they are not important for this post.
2. Add a new contact in your iPhone called Twitter. The phone number for it should be 40404. Note that this number works in the U.S. It may be different for other parts of the world.
3. Using Siri, say something like “Tell Twitter, This is a tweet from my phone.” And then Siri will send a text message to the Twitter contact which effectively tweets what you say.
Hope this helps someone.
