By default, the BlackBerry® Smartphone Simulator does not check for required code signatures and it does not prompt you before connecting to the network. Before you deploy your application, test it in secure mode using the BlackBerry Smartphone Simulator.
When you enable BlackBerry Smartphone Simulator security, you cannot use the .cod files that come with the BlackBerry Smartphone Simulator. You must use the .cod files that are installed on the actual BlackBerry device. To obtain the appropriate .cod files, copy BlackBerry device .cod files from your computer to the BlackBerry Smartphone Simulator installation folder.
By default, the installation folder exists in the following location: C:\Program Files\Common Files\Research In Motion\Shared\Loader Files\Handheld\Java.
