undetectable Blacberry curve 9300

Two days ago, I installed mobile joomla 1.2.0. I myself use blackberry curve 9300. Yesterday, I could accessed my website well but somehow, I clicked a sentence on its footer and as a result the appearance changed. Now I cannot access my website in mobile joomla theme on my blackberry any more. Would you mind giving me solution, guys?

Most likely you clicked on Full version link. To switch back to mobile mode, visit yoursite.com/?device=xhtml

I see. Thank you.

I can access my mobile website again. Thank you very much indeed for your help.
