Thanks for the help.
I currently have a D2 and am thinking about upgrading to the D4. Since the latest Android version prevents 3rd party apps from changing the GPS state (I have the Tasker app which I use to do this for certain things), I know that I will have to root the new phone (and install Secure Settings) in order to be able to control the GPS via Tasker. Will the Droid 4 Utility that I found here in the forum work on the latest D4 system version? I've read in other forums that Google removed the root exploits in the later system versions for the D2 and want to make sure that a similiar thing has not been done for the D4 before I spend the money (and time) getting a new phone and trying to root it (don't want a $200 brick).
