E90 is not available in Europe (don't know for Asia), too many issues with microphone and keyboard, Nokia stopped the sales and no informations are available on availability.
You can try the "mobile webinterface" with it and/or with E61 and/or with N810.
I like the idea of "global interface" but it means that you'll need to have data network available (and working subscribtion) each time you want to get contact informations or check your calendar.
Unless you use a connector (Mail4Exchange or RoadSync) to sync calendar/contacts and use the Mobile webUI to browse mails... |
