Nokia E75 does not redirect from website to mobile website

HELP!
When I try to access the mobile website, I still get the normal website on my Nokia E75. It works fine for other phones, iPhone eg. This is not good as the top brass in our org use Nokia E75. Any ideas?

What is UserAgent string of NokiaE75?
PS. You can get value of the string here: mobilejoomla.com/ua.php (visit it by phone)

My user agent when I wen to the website with my Nokia E75:
Mozilla/5.0(SymbianOS9.3;Series60/3.2Nokia E75-1/211.12.01;Profile/MIDP-2.1Configuration/CLDC-1.1)Apple WebKit/525 (KHTML, like Gecko)Version/3.1BrowserNG/7.1.1

Hmm. Both Mobile-Simple and Mobile-TeraWURFL detectors correctly detect this device as xhtml-compatible. So, recheck your MobileJoomla settings (maybe you set use of default template for such a devices).
And what is url of the site?

I have checked the Joomla settings and it all seems in order. The url is www.cogta.gov.za (this is the actual website.) When accessing it from a mobile, it should redirect to pda.cogta.gov.za. It does if for most phones, but not all.

i get the normal site too. not mobile.

Mozilla/4.0 (compatible; MSIE 6.0; Windows CE; IEMobile 6.12; en-US; KIN. Two 1.0)

Any ideas why this would be so?

Still cannot reproduce the problem. It seems (99%) that it's caused by smth outside mobilejoomla: maybe additional caching extension, maybe caching reverse proxy, etc.
