I just read over at BlackBerryCool.com that RIM has relaunched their mobile BlackBerry web portal. The site is only accessible from the BlackBerry's web browser, unlike Palm's mobile portal that is accessible from the mobile or the desktop.
"I’ve just received word that RIM has completed a fairly significant relaunch of mobile.blackberry.com, their all-in-one web portal for BlackBerry users. The new mobile.blackberry.com features a much more user-friendly design, requiring fewer clicks to get where you want to go, as well as faster load times."
