not sure what you're typing into the url address bar but you may want to try:
go to MSN.com and click the hotmail link from the top of the page.
i have no problem accessing hotmail but when i delete messages, I often get a blank white screen and i have to "pull" the other messages down from the top of the page by flicking down with my finger.
also, it is easier to maneuver around hotmail if you make sure your browser is accessing the site in the mobile mode rather than the full web mode.
