I had to transfer contacts from an Blackberry (BB) to an Nokia
I tried to copy the address book in BB to SIM card and transfer them to the Nokia, but that option is not available in BB, its only the other way from SIM to address book.
Nokia PC Suite doesn't have an option to import CSV, XLS file either.
After little bit of research on the web, got an simple solution which works :-)
As the BB contacts are synced with Outlook, I had to export the contacts to VCF file
"Export Outlook 2003 Contacts as vCards"
Microsoft does not offer an 'Export as vCard' function in Outlook 2003 (simply dragging and dropping contacts into a Desktop folder results in .msg files), there is a workaround:
Select all contacts in Outlook
Click Actions -> Forward vCard
Select all of the attached vcf files in the resulting email message and drag to a folder on your Desktop, or simply send the email to yourself.
That's it - the vcf files are ready.
Now open Nokia PC Suite, connect Nokia 6300 to the USB port
Open Phone Browser and go to Contacts
Now Copy and Paste the VCF files in earlier step to the Contacts folder.
Problem I faces is, duplicate contacts are not overwritten, one more contact is added, thus causing duplication of contacts, so deleted all contacts from Nokia phone and copied all BB contacts.
Just copy and paste works mate... ;-)
