The Samsung Galaxy S phones have been experiencing issues with their GPSs. So you may be interested that the new Samsung Mobile tweeted and is still tweeting about a "GPS Restore Application" that it's thrown together for wiping the GPS subsystem and making it factory-fresh. But how helpful will this be? Restoring a screwed-up GPS to its original screwed-up state.
Here is Sammy's confusing verbiage:
"During online surveillance, there is an abundance of GPS tweaks that impair GPS performance. Often times, no backup is performed to restore values prior to modifications. Samsung has released an application that restores GPS settings to recommended factory defaults for optinum [sic] performance."
