Is there any open world game like second life on iPhone?

I just want to know if there is an online 3d avatar game like second life on iPhone.

Minecraft

You can participate in Second LIfe through an iPhone browser created by Comverse (see link below) or there's also Pocket Metaverse that works pretty well for messaging, inventory access, etc. Another, formerly called Ajaxlife (now available on github). (See links below for details on all.)
