If you've been waiting for Citrix Receiver to arrive on BlackBerry 10 the wait is over, sort of. Just like when it initially launched on the BlackBerry PlayBook, the app has now arrived via a technology preview, meaning there is still some things missing. For now though the feature list includes everything that is currently available on the PlayBook version including:
As for what's missing, because that's as important as what's included, there is no rotation and the pinch and zoom functionality is only available within the published resource but it should all be enough to get you up and running. Keep in mind, Citrix Receiver for BlackBerry 10 is currently only supported on the BlackBerry Z10 and BlackBerry Q10 for now.
