Blackberry CURVE 8350I - Manual (Page 206)

Custom contact list field data is not appearing on my computer
You can only synchronize the data in a custom contact list field with a text field in the email application on your computer. For example, you
cannot add a contact's birthday to a custom contact list field on your BlackBerry® device and synchronize it with the email application on your
computer, because the birthday field is a date field in the email application on your computer.
Some characters in calendar entries do not appear correctly after synchronization
If you schedule appointments or meetings on your BlackBerry® device that contain special characters or accents, your computer might not
support these characters.
On your computer, verify that you are using the correct default code page and that the correct font support is installed on your computer. For
more information, see the documentation for the operating system on your computer.
Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you update any software.
Maintaining an up-to-date backup file on your computer might allow you to recover device data if your device is lost, stolen, or corrupted by
an unforeseen issue.
