This is my favourite secret mobile Phone tricks out of the list. When you have everything set up, you’ll be able to send a text message with a chosen keyword such as “˜shutdown’ to your PC. This then activates the Shutdown procedure. Here’s how it works.

First, you create an easy Text File with a one line command (this is specified in the video) and save it to your hard drive. Then, you set up a Kwiry account and sync it with your Email account which you have set up in Outlook Express.

A rule must then be created in Outlook Express which will detect any incoming emails with that keyword and then execute the shutdown command in the text file when it does.

By sending a text with the keyword to your Kwiry account, an identical email is sent to your own email account, thus you can shut down your PC via SMS when you’re out and about.

It’s best to choose an obscure word so a normal email doesn’t accidentally shut down your PC.

You could also use this for cueing up a video game or a program which takes a long time to load before you actually get home to your PC by choosing another application besides from the shutdown file when creating a rule.

Just a quick word of warning before I sign off: many of the claimed Cell Phone hacks on the internet are completely fake. When researching this article (and through some SPAM a few years back) I came across lots of bogus guides which either waste your time or potentially mess up your phone. So watch out!
