The PlayBook version works just about perfectly. I notice some stuttering in the transition animations and the QRcode scan doesn't work because the BlackBerry OS doesn't support the intent correctly. Otherwise you should be good, but if you find any issues please let me know and I will take care of them.
I have submitted the app to BlackBerry AppWorld and am waiting for BB approval before it gets posted. Last time I did this it took about a week. I'll let you know as soon as I get the release notification.
