I am on T-Mobile, using pIE browser.
I can access the HTML based my.yahoo.com (can login into my account and view my page). But cannot access the wap.yaho.com. It shows the Yahoo! Worldwide page with links for all the countries and then when I click the link for any of the country, it tries connecting and stays put at the same page. :-( A month or so ago, I could view the WAP pages and check the news etc.
Looks like Yahoo! has changed the WAP page code generation. There is some tag in the page that is breaking the pIE browser.
