Microsoft rolled out "Exchange ActiveSync support for Windows Live Hotmail" -- that "keeps everything in sync between your phone and Hotmail, so whatever you do on your phone, like delete an email, add an appointment, or update one of your contacts with a new number, will also be reflected on the web, and vice-versa," writes Microsoft.
According to setup page, supported devices right now include Windows Mobile 6.x phones, Windows Phone 7, iPhone, iPod touch and iPad, in addition to Nokia E-series, S-series, N-series running Mail for Exchange app. Support for Google Android devices is in testing.
