The Second Life client for your mobile phone.

The new released version (1.6.452) now supports teleporting to avatars in the same region. You will be teleported 2m to the east of the the selected avatar. This should make it possible to chat with everyone in the region and follow people to special places. I think it’s the best way to move without seeing.

Also new is the group notice feature, but at the moment only the message itself is displayed in the appropriate group chat channel, the attachments are not saved to your inventory.
