Most users in India, Brazil
Google has introduced an iPhone app for Orkut, one of the company's lesser-known social networks. While virtually invisible in North America and Europe, the network still has about 66 million users worldwide, 80 percent of which are based in India and Brazil. Google currently throws most of its weight behind Google+, which started in late June but already has over 62 million users.
Much like other social networking titles, the Orkut app lets users update their status, follow friends, and check messages. Users can also browse "scraps," reply to friends' birthday notices, and snap photos and upload them directly to an album. The title is a free download, and requires only iOS 4 or later.
