Editor’s Note: Last year one of our most popular articles of the year was written by Shara Karasic, who pointed out 10 small-business apps for the iPhone. The response was so enthusiastic, that we invited Shara back for an even bigger and better roundup of apps for entrepreneurs and small-business execs this year. And who better than Shara to contribute this article — she lives, breathes, sleeps and eats apps in her role with Appolicious, a community review site for mobile apps. Here in 2011 we are delighted to bring you Shara’s much bigger list of iPhone and iPad apps, organized by type of activity.
Since I listed 10 great small business apps in 2010 , the use of iPhones and iPads for SMB’s has exploded in areas from business travel to communication to productivity. The office has become truly mobile. Here are must-have apps for those running and operating businesses in 2011:
1. Travel for Business Like a True Road Warrior
Prepare for your trip and navigate like a true road warrior using your iPhone! Kayak PRO  lets you find a flight or a hotel; TripIt – Travel Organizer  keeps your travel itinerary always handy in your pocket,; FlightTrack Pro – Live Flight Status Tracker  gives you real-time flight updates and helps you find alternate flights (and works seamlessly with TripIt); GateGuru  will guide you to the nearest ATM, post office, or luggage store in the airport. Once you arrive, Taxi!  makes it easy to find a cab 24/7 anywhere in the U.S. Don’t forget your Kindle  app so you can read on the plane or in the taxi.
2. Business Communications that Join Virtual Teams
Make free phone calls with Viber , Truphone , or Skype , which has entered 2011 with the ability to make video calls over both Wi-Fi and 3G.
