Calling all devs! If you have a few minutes to spare, take a few clicks and help complete the App Developer Survey. The survey will be used to help understand the current mobile apps ecosystem as well as the thinking of mobile developers. You'll need to have developed mobile apps already as you'll be asked questions along the links of type of app and number of downloads. The survey only takes a few minutes and upon completion you'll be entered to win a BlackBerry PlayBook. So if you're a developer then spare a few minutes to help the community and chime in with your answers.
