It didn't created it, but I:
1..- Installed a standalone Joomla site on my desktop
2.- Install the mobile Joomla Component
3.- Verify is everything was ok (it was)
4.- Install the mobile joomla on my "alive" site
5.- backed up the tables from mobile joomla in the database of my stand alone installation (with drop option, thanks to phpmyadmin)
6.- Restored table from my database in "alive" site
7.- Restart S.O. (I have Windows... so the habit LOL)
8.- Run the site on my Android 2.2
9.- Check error_log in site, and behavior of tables (nothing weird found).
10.- ¡Good job pal!
This is some one else wants to try in that way, it is not the best, but mobile joomla is great and I won't lose the opportunity to use it. Thanks developers
