Hi, I'm considering buying a GPS phone (specifically G1) to get as a side effect a GPS unit I can use while travelling in the deep desert, so that I can collect track/log data for later, offline geolocation of photographs I take on the trip. I specifically do NOT need maps, navigation, and all that urban GPS rot. I just need some way to record either the raw NMEA data (ugh) or some reasonably nice app that simply logs GPS data for me in a place-nice format. I'm trying to avoid buying a standalone GPS unit, since all I need is the GPS log and who needs more gadgets with power cubes, cables and adapters to live with? I'll be off-network for 2, 3 days at a time, I can keep the thing charged and all that. With all the marketing noise it' shard to find any real specs on GPS and other sensor data. Any help in this direction would be helpful. Thanks!
