Every thread on every forum seems to have a different combination of settings, all with mixed results. I'm wondering if any of the settings are really making any difference at all, or if everything is just coincidence (ex: was able to lock instantly after changing settings, but that's only because you had a previous lock a minute ago, which allows you lock on faster).
edit: Someone also suggested somewhere that maybe these settings may only affect the GPS test application within the console, and that they aren't permanent settings that affect the way other applications (e.g. Google Maps) work.
