Orkut silently releases the mobile version.

The title says it all. You can see the mobile version at http://m.orkut.com.
Using the mobile version you can:

• See all your scraps
• See all updates from friends
• Search for friends
• Write scraps
• Respond to friends requests
• Get birthday reminders

Most part of the site is easily accessible through shortcuts. Communities are not currently supported but will probably be when the site is officially released by Google.
