Ok I did a search (before I got belittled by anyone) on this and nothing really on this exact topic.
When I press alt+back button to see all my running apps, the browser always shows. Eventhough I've completely closed it. Is that normal? Does the BB need the browser to always run for BB data? I just think that's kinda weird.
If you hit menu>close in the browser, it's not running. You can even use crackutil to completely remove the browser and the icon still shows in switch applications.
