Recall that Matt Sheehan and crew from Webmapsolutions.com has been working on app development with the Blackberry Playbook – see the article Flex 4.5 BlackBerry PlayBook & Geolocation. Since publishing that piece Matt has been hard at it and has continued developing for the Playbook. Most recently, they’ve completed the first phase of development on an ESRI ArcGIS mobile AIR application running on the BlackBerry PlayBook. This video demonstrates some base functionality of the app. See more details at http://www.webmapsolutions.com
