How do I set Google Latitude to auto-update with location regularly? When I use Google Maps it sets my Google Latitude location, but once I turn Maps off it stops. I'd like it to update with my location on a regular basis. I don't want to drain the battery by always using the GPS, but it'd be nice if it updated, say, every half hour or so.
I found this from the Google Mobile Help forum after a little searching. It's from 8/15/09 so I actually see something a little different on my phone Settings > Location > Google Location Services. I haven't tested it but hope it helps.

Quoting the site:


  Hi everyone, Apologies for not
  updating this thread specifically
  sooner. There is a new version
  available in Android Market (version
  3.1.2). Just search for "Google Maps" if you have at least the 1.5 system
  update (Cupcake) and install this over
  your current version of Maps.
  
  Please let me know if you experience
  background location updating issues
  with this version. As long as you have
  enabled automatic location detection
  in the Latitude privacy menu and have
  enabled location detection (Settings >
  Security &amp; location > Use wireless
  networks), Latitude should update your
  location while your phone is on. This
  means your location should never
  appear older than ~1 hour to any of
  your friends.
  
  Thank you all for your patience! Chris
