3rd party app permission (Poynt)

I have been thinking about BB security (more specially, 3rd party application permission). I don't know if it is overkill to change from the default setting as it is stated on Blackberry's website that (bold is my emphasis)

If you have added third-party applications to your device, the device firewall is designed to prevent these applications from sending or receiving data without your knowledge. Before a third-party application sends or receives data, a dialog box prompts you to accept or deny the connection request.

I made changes to fit my preference and I am passing the information along.

Connections

USB: Set whether third-party applications can use physical connections, such as a USB cable or RS-232 cable, that you have set up for your BlackBerry device.
Default: Allow.
My setting: Deny.

Event though this is set to "Prompt," the application never asked for permission to access the Internet; access is just given.

Cross Application Communication: Specify whether third-party applications can communicate and share data with other applications on your BlackBerry device.

I am not sure what "Application Management" means. Does it mean that this 3rd party app can add/delete/view modules from other 3rd party app or just itself or both? App still works fine with "Deny" setting.
