If you want to change it once and only once, the best place for this is in your application.
You can add:
<key>UIStatusBarStyle</key> <string>UIStatusBarStyleBlackTranslucent</string>
or when viewed as a list of properties
Status bar style Translucent black style
Just right-click and "Add Line", the "Status Bar" style will be available, with a transparent black style as the available field.
