I love web apps specially the ones like Pingie which is a very useful and absolutely free to use service .
Pingie is a cool utility that lets you get notified via SMS whenever the sites you are subscribed to get updated. You basically subscribe to a site’s RSS feed and your phone works as the RSS reader.
Pingie only requires your email address to signup and it is absolutely free of charge to subscribe, however your cellular carriers may charge you for the SMS messages you receive. Its a good idea to sign up for an unlimited text messaging plan before you start using Pingie.
Pingie also has a feature for publishers where they can add a widget-type of box to their blogs where users can sign up and subscribe to the feed via SMS.
