A new set of extrapolated data from location network developer uLocate suggests that active users of the Droid may have more than doubled in the first week of sales. Third-party estimates indicated that Verizon may have only sold 100,000 launch units, but uLocate says it will have detected about 25,000 new Droids on its network by Saturday. As uLocate's information usually represents about 10 percent of the actual user base of a phone when it's new, the figure would translate to about 250,000 total Droid users.
