Don't update Google Maps on your Android device until you have read the reviews of the new version. Most recent review are very poor, giving it just one or two stars.

minimal warning. Although the official end date is August 9th, this update removes Latitude functionality completely.
Many Google users are already smarting over the loss of Google Reader and iGoogle. Now it seems that the Maps functionality has been downgraded and Latitude terminated. What next? Perhaps it's a good time to start looking at alternatives..
