Can I go online from my mobile device?
Yes & No! - There currently aren't any 'full blown' viewers available for any mobile platform, however ther is a cut down viewer called Lumiya that works on Android devices. It is very good for keeping up with chats and instant messages messages and does have a 3-d view although I havn't had much luck with that!
For iOS users, there is MetChat although it seems to have mixed reviews. If anyone has used this please do send us some feedback as to how well it works.
