Not only will BlackBerrys be helping you to get on the plane in the first place, but soon they’ll give you something do once you’re in the air, too. Jetblue will be offering free Yahoo! instant messaging and e-mail access for free to BlackBerry users on one of their flights next week to test out in-plane Wi-Fi access. The Airbus A320 dubbed BetaBlue will start the testing next Tuesday on Flight 641 from New York to San Francisco, with the eventual goal of an airline-wide rollout. Of course, once the program goes live, you can expect some pretty hefty fees to be tagged onto data usage – just pretend you’re in Canada.
