Quick Tip: Unistalling BlackBerry Playbook application
The most common way to uninstall app from playbook simulator is using -uninstallApp flag within blackberry-deploy command. The bad thing about it is, that command requires installed .bar file or package-id that noone remembers:
blackberry-deploy -uninstallApp -device 192.168.44.129 -package MyApp.bar
Fortunately, there is another undocummented method mentioned by peter9477 using simulator’s http server. To make it work is very easy…
- swith simulator to developer mode and grab ip address
- open any web browser and type https://192.168.x.x/appInstaller.html (use ip of your simulator)
- accept SSL certificate
- now you should see html interface
- click button “List” under “List all installed apps”
- now you should see list of installed apps
- copy Package Id and Package Name into the “‘Other actions” form on previous page
Here is a screenshot of appInstaller.html interface

On my machine it gives 404 Not Found, my simulator is on development mode
hi Z, it seems like this feature is gone with simulator beta3 and later
