I submitted a new PlayBook app to App World earlier today, and I noticed that RIM made a small change in preperation for BlackBerry 10. This Dropdown menu formerly let you choose between OS4, OS5, OS6, OS7, or TabletOS. As you can see, it now lists BBOS and QNX.
While little things like this aren't unexpected, but it's good to see these little signs of RIM moving along towards a BB10 release. Hopefully BB10 BlackBerrys will popup in the list of devices you can submit an app for soon!
