I'm looking for a cheap hack to text myself alerts whenever my server is down. (I know there's services like Nagios etc, I don't want to get into that.) I'm already sending out emails, so I'm looking for a quick way to add my phone as another recipient to the list of emails.
I know individual carriers have different ways of doing this, but I'm looking for something apple-specific since all of the members on my team have iPhones but with different carriers.
