Anything that can text geocoords? I'd like to text someone my location so they can use something like maps.google.com and navigate to me. Any app or technique that makes this task easier than putzing around asking for the address?
Google maps can do this.  Long-press the map at your location; a popup should appear with the address; you can tap that and it'll give you the option to "share" that location.  From that you can send a text, email, etc.
