What took so long? Obama '08, the iPhone app, is free. Sort of: There's no charge, but the app will try to put you to work dialing friends in battleground states. CNET non-Democrat Declan McCullagh test-drove it: "The application ranked contacts in Colorado, Michigan, and New Mexico at the top; at the bottom was a friend whose cell phone has a Texas number, though she actually lives in California." The app's controversial feature is that it reports back to Obama Central on the total number of calls you've dialed.
