The artificially intelligent voice that made headlines with the launch of the iPhone (News - Alert) 4S is hitting the news once again. The buzz is that you can hack into your own Siri to do more than just her specified to-do list. In fact, a video is going around showing users how to get Siri to change the thermostat, amongst other things.

A video has been leaked online that demonstrates Siri adjusting a thermostat with the power of voice. Much like getting up to physically change the channel on a TV, gone are the days of getting up to manually change the temperature in your own home. Just shout orders at Siri. Job done.

Twitter (News - Alert) user @plamoni developed a third-party proxy-server, which means in conjunction with a WiFi (News - Alert) thermostat, the temperature of your house can be controlled remotely by voice. It’s like something out of Tony Stark’s hooked up pad, but with a lot less features.

The hack builds on previous efforts from Applidium, a French mobile developer company that last week figured out the protocol behind Siri. It turns out that Siri could theoretically run on any device, not just Apple's (News - Alert) latest handset, but the servers will only respond when provided with an unique ID number tied to each individual iPhone 4S.

More commands are being added daily, with a Twitter module already included. Best of all, this only requires the installation of a fake root certificate onto the phone. The proxy software is available on GitHub along with instructions, though for now the developer warns that it's not for the faint-hearted.

Siri’s an amazing advancement in the way that we interact with out iPhones, but it doesn’t exactly do everything you want it to do out of the box. You can’t make a Facebook status update, send a message to Google (News - Alert)+ or even tweet, which is doubly absurd given iOS 5’s native Twitter integration.

One hack exists that lets you do all three with Siri.

Techland gives us a great run down of easy Siri hacks that will get you up and running with voice control Twitter, Facebook and Google+ in no time.

“For Facebook, text ‘Hello’ to 32665 in the United States (or the short code for whatever country you’re in), then follow the link in the reply to finish the setup process. Add the short code to your Contacts, and name it ‘Facebook.’ That way, you can tell Siri to ‘send a text to Facebook saying…,’” writes the report.

There seems to be an entire website dedicated to hacks just for Siri. Sirihacks.net tracks the latest and greatest “enhancements” for the technophiles out there. Although, in actuality, there are no real “hacks” listed on this site, just a few plug-ins that allow Siri to do a little more.
