Mobile Web Forms Development

Hello ,
i have developed a mobile web form page and now i want to test it.
I can tested it successfully using Internet Explorer by browsing
the .aspx webpage.The problem is that i now try to test it using
the Nokia Mobile Browser Simulator and i cannot see the webpage.
Are Mobile Web Forms not supported by Nokia ? If not which
mobile phones support viewing .aspx webpages?

Thanks !

i downloaded the phone simulator from www.openwave.com and now it works.
it does show the mobile web form page.
by the way are mobile web forms supported by many mobile-cell phones or is it not worth
developing because of lack of support ?
Is java supported by more phones?
