I am a blackberry user (sounds like a drug, s'pose it is in a way), back to the point, for the blackberry you do not provide too many permissions to the App, so it has not really been an issue, however I fully understand your concern. There are lot of Android users on this site who know their way around the OS, so I am sure that somebody will respond shortly.
Love is better than anger. Hope is better than fear. Optimism is better than despair. So let us be loving, hopeful, and optimistic. And we will change the world. - Jack Layton (1950-2011)
