I tried to delete it from the applications list, but it did not show up. To hide it,
1 just click on "options" to see all the applications you have on BB
2 then scroll to the app you want to "hide"
3 click on options again and choose "hide" option
Unfortunately, it does not really hide the application as it will just have a faded look to the icon when it is on the desktop.
The other option you can do is create a new folder by clicking on options and then just moving the icons you have no use for into the folder to clear up the clutter.
