This means the one feature the BlackBerry has (which I didn’t realize until about 2 months ago), Windows Mobile now has. Awesome! I no longer have to copy down every e-mail address I might ever want to use from my mobile device.
Now Sprint & Motorola better get it together and announce support for WM6 on the Q, so I can go purchase one. I assume they’ll have to since, Moto just announced the GSM Q, and it’s running WM6.
UPDATE: - This functionality is present on the Sprint Q, you can search online for contacts in your Global Address Sever on Exchange!
