For the few of those with the hard-to-find LG eXpo (more on that later), there are three interesting applications hidden within \Windows that may be of interest:
GPSViewer/GPS Utility is a simple app that shows you the number of satellites found and their strength, all in a nice graph form. (Of note is excellent GPS reception and accuracy on the eXpo). It also gives your current speed, albeit in km/h. Still, not a bad diagnostic tool.
"WifiEngMenu" is an advanced WiFi diagnostic tool that gives a ton of information related to your current network, including transmission rate test, WWM PS test, signal strength, etc.
Finally there is Tascal Registry Editor, a common (and ancient) freeware registry application. While nothing special, it's nice to have it readily available.
To access these apps, the first two (GPS Viewer, WifiEngMenu) require you to find them under \Windows and create a shortcut to the Start Menu. To make that easier for folks, we'll include the shortcuts for you to download directly: just unzip to \Windows\Start Menu and you should be all set. For the Registry editor, find "TascalRegEdit.cab" under \Windows and simply run and install. A shortcut will be created for you to use directly.
