Windows Live:
    Windows Live functions including the Market don't work.
    To sync contacts/calendar/emails you need to manually set up

    possible to sync with Outlook.


Hard reset:
    During boot, when "1234" appears on screen, press and hold VolUp + VolDown,
    until the message appears. Press VolDown twice to clear data.


SD Card:
    The SD Card will only be available to the OS if it's inside the device during
    its first boot. Removing the SD Card will destroy all user data
    and a hard reset is required!

    NOT all SD Cards are compatible with WP7.
    If your card isn't compatible with WP7, it won't be used for data storage or
    it may cause random reboots.

    WARNING: WP7 will format the SD card during the first boot.

    is used as RAID with main memory.
