ATT BB9700, normally get GPS location by a long series of menus and keys. How do I get "GPS location refresh" to a convenience key?
You can't
The closest you can go with a convenience key is to Options.
If this is so important to you, then just open the GPS Settings, and instead of closing it after refreshing your GPS location... leave it open by hitting the red call end button
Now if you want quick access to the GPS Settings, just press the Menu button and bring up App Switcher. Click on Options (wrench icon) and you're there
