Speaking at the Mobile World Congress event in Barcelona Spain, Google VP of Engineering Vic Gundotra apparently said that Google’s mobile friend finder service Latitude had seen “more than a million” mobile subscribers sign up for the service in the first week since launch on February 4.

Given that Google released Latitude in 27 international markets simultaneously and for multiple mobile platforms that’s not necessarily off the charts, but it’s a massive number for one week in my view.

We’ll see if the momentum holds and it continues to gain users (the iPhone version has yet to come out). The service is “viral” so as more people sign up for it and use it they’ll encourage their friends to do so also.

For some context, MySpace has said that roughly 15 percent of its traffic is coming from mobile devices now, while Facebook claims 25 million mobile users with four million “active daily users.”
