which is the OS version installed in your device.??
I've seen some apis that may help you but you need to have a 4.2.1(or above) version device.
Here are the classes in 4.2.1 api-javadocs that may help you out, please check them out.:
class net.rim.device.api.applicationcontrol.ApplicationP ermissions and
class net.rim.device.api.applicationcontrol.ApplicationP ermissionsManager
Hope this helps you.
