Hy,
First excuse me for my english.
I've made many test, but I don't understand.

If I check my site with MobileOK w3c validator, my MJ don't switch to correct template.
If I check www.mobilejoomla.com all work fine.
Googlebot-mobile do the same too (in XHTML and cHTML).
Why?

I was obbligated to use subdomain and I was obbligated to add more that one sites to google with more that one sitemap, with more that one robots.txt to disable mobile or web type of site in anyone of that.

Can anyone help me, please?

Maybe I must update terawurfl db? How?

Windows 2003 server
IIRF rewrite module
PHP
MySQL
Joomla 1.6.3
MJ 0.9.12
etc...
