Cell phone users increasingly rely on their mobile devices for more than calling and text messaging.  And even beyond calculators, games and GPS, there are hundreds of smart, practical and fun applications that are worth a try.

Here’s a variety of applications that can make your smart phone even smarter.

Turn Your Phone Into a Radio

Not happy with your local radio stations?  Build your own on your cell phone with Pandora Mobile.  Just like on Pandora’s web site, you can pick the name of your favorite artist or song to create a “station,” and Pandora will play music that it thinks you’ll like based on an extensive database on trends in melody, harmony, instrumentation, rhythm, vocals and lyrics.  And you can refine your preferences with a thumbs-up or thumbs-down rating on each song.

With Pandora on your phone, you can listen to all the stations you created on the web and create new ones that will appear online the next time you're back at a computer.

Available on: Research in Motion Blackberry devices via Blackberry App World (though it’s not yet available on the Blackberry Storm) (Stock Quote: RIMM) or through Pandora’s web site, your Apple iPhone through the iPhone App Store (Stock Quote: AAPL) or on Microsoft Windows Mobile phones (Stock Quote: MSFT) through Pandora.com.

Price: Free.
