If you are trying to access the web site to obtain your email, which is really the only reason I can think of to do so, then read on as this will enable you to get hotmail to the x10 as well as live email (Which is actually the new name for Hotmail).
Go to the MARKET and download the FREE app called, "MAILDROID". With this app, you can get your email programs to work. Plus there are MANY advantages to the program as you'll notice once you install it. I have been using it since Aug and just cannot imagine using the X10 without it. Mind you I still use the DEFAULT email program for everything except YAHOO, but that is only so the other features on the X10 that require the default email program to function so they can function. I loaded up the email clients on the default and that was all. I do NOT use it for any other function, as Maildroid does everything it does and more. The only thing Maildroid does not do at this time is to intermingle with the other apps on the x10.
Good Luck!
