Hi,
I need Mybb mobile theme which can't changed original content and not missing any tool.
You can always try this one
http://mybbgm.com/
you have todownload from there but it is a free download.
I am currently working on one mobile theme for MyBB.
It is gonna be awesome.
There is no release yet. As it is not fully done.
PM me if you want me to send you a PM when it is done.
I have made one released for free right here:
[link died, pm me]
EDIT: link died.
Any more free options to go mobile with MyBB foruns?
