GPS App v1.1
A J2ME app for your cell phone that converts the lat/long from your GPS into UTM for the NAD27 datum suitable for use with USGS topo maps. Also displays altitude in feet. It should work with most phones as long as the provider hasn't locked down the Location API (though many have, including my provider, AT&T). If this is the case you'll have to search for a hack to enable third-party applications to use it. Unfortunately the only way you will know is if the app never gets a GPS fix. :-(
