Well, the question is a misdirected one. The reason question here is, does the N900 have a transfer contacts option? Or even an option to export your contacts to a vcf (vcard) file like Apple, Palm and every other device (including the N800) have done for over the past two decades? If so, then you could upload your contacts to http://contacts.google.com. Once they're in your Google Contacts list, they'll automagically appear on your Android device. I tested transferring my contacts from N900 to Galaxy Tab. In N900 there is an option to export all contacts as vCards (versions 2.1 and 3.0). You must be viewing the list of all contacts when this option shows in the menu. Export asks for a folder name and saves each contact as a separate vCard file in that folder. The files included all my contact fields (all phone numbers, regular an email adress fields etc.). In the next step I copied all vCard files to my MacBook Pro. Then I imported them in Apple Address Book by selecting them all and opening in Address Book. From Address Book it is possible to export all contacts as a single file. The last step was to import that one file to Google Contacts. Now I finally had all my contacts transferred from N900 to my Galaxy Tab.
