What: A nifty add-on to your phone that lets you make Internet calls to fellow Skype users without being attached to your computer. (A Wi-Fi connection is required.)


Why: It keeps the grandparents happy and up-to-date with my little prince’s development—and wardrobe. Not to mention it’s good for the environment: no phone bills or carbon footprints. Earth Day is tomorrow, don’t forget.


Where: Free on the iPhone.
