>Has anybody successfully read UT on iPad? A few days ago I borrow my wife's ipad and tried to log into UT but it didn't work. Was I doing something wrong or UT is for IE only?

This has not been tested yet. In fact, the HTML5 version is not even ready yet. But, as far as browsers, UT is pretty much ok with most browsers now. But, as far as those pad devices and smartphones, no test has been done on any of that yet.
