Now that the BlackBerry 10 Alpha Dev device is in the hands of the developers you can expect to see more and more of this kind of stuff. We are on the grou nd at BlackBerry World and just got word from @FortNeyland95 that he now has email working on his BlackBerry 10 Alpha Dev device. When RIM presented the devices to the developers they informed us that email would not work, but you know how developers like to break the rules.
Also some of the phone functions have also been enabled, and while you cannot place calls you most certainly can receive them.
We have confirmed that this is the Android email client that has in fact been enabled, as well as some other Android apps and not the actual BB10 email client. This is all thanks to the Android runtime being enabled. We will continue to bring more news on these developments as they occur.
