No sense how mobile tools work with my project

Hi,

Im working on a cliente project, adapting his drupal website to mobile view.

I installed mobile_tools, browscap, wurfl and fusion_mobile.

I have all finish, all blocks like i want, some changes with dinamical javascript to avoid elements that in normal theme are not showed.

But since few days i cant handle a problem that is happening in the website, and finally i must answer to you...i try to explain my better:

CASE 1
If i select wurfl at both external modules option and i enable:

Switch theme for a mobile device *
Automatically hide address bar in mobile theme (uses javascript and only work on javascript enabled devices)
Add Mobile Tools header
Enable filter for this device group

And select the same theme in both "selects".

CONCLUSION: The website looks perfect and in a mobile theme, when i finish work and go home, few hourse ago, i check the web in a mobile device and again it looks like original web of pc browser.

CASE 2
If i select wurfl at both external modules option and i enable:

Switch theme for a mobile device *

The theme in the "select"

CONCLUSION: The website looks perfect only in few sections as a mobile theme, is other sections load the default theme of the website.

CASE 3
If i select browscap and wurfl as external modules option and i enable:

Switch theme for a mobile device *
Automatically hide address bar in mobile theme (uses javascript and only work on javascript enabled devices)
Add Mobile Tools header
Enable filter for this device group

And select the same theme in both "selects".

CONCLUSION: Some sections looks good, other show normal theme, differents sections that case 2.

------
I try diferents configurations like those, changing options, droping all the modules are useless for mobile theme....and im going crazy...

Sometimes i see the website as normal theme in a mobile device, and 30 minutes then, without changing anything, i can see perfectly the mobile theme on a mobile device.

I try to explain that is no sense or logical issue i can trace or find...dont understand why is so random that the mobile theme works or not...maybe i forgive something...

My final option testing on a m.website.com when i get the subdomain...but i dont know what do...

Thanks for your attention.
