It does lock you out of using gps programs other than the VNavigator. I cant remember how exactly to revert back to a previous spl as i believe that was what got overridden with verizons stuff. have you tried searching? I remember there being multiple ppeople trying to help that. There was a thread I started on that....but it was like hella months ago. I do know though that you have a high risk of bricking your phone, so make sure your read up before you do anything. good luck =)
