Ok, so I did get all my details imported via the wizard. It took a couple of attempts. For my old school Nokia 6230i, the CSV file is pretty comprehensive.. there are columns like these, and many more:
"Title","First name","Middle name","Last name","Suffix","Job title","Company","Birthday".....
Most of the fields are not populated of course, since the phone didn't have features for most of these.
When I did the mapping to the Samsung format (in Kies), my mapping selections were (CSV -> Samsung):
"Last Name" -> "Last Name" (this is default, leave all the defaults)
"Notes" -> "Memo"
"General Mobile" -> "Phone Number2(Number)" <Mobile*>
"General Phone" -> "Phone Number1(Number)" <Mobile*>
"General Email" -> "Email1(Address)"
"General Fax" -> "Phone Number5(Number)" <Fax*>
"Home Phone" -> "Phone Number3(Number)" <Home*>
"Business Phone" -> "Phone Number4(Number)" <Office*>
"General Street" -> "Address1(Home/Office)"
*There is a little check box in Kies marked:
[ ] Select TelephoneNumber Type in person
This is typically undocumented
If you check it, you will be able to select the designations in angle brackets given above (Mobile, Fax, etc). I recommend doing this, else the numbers in your Samsung while just be type "Other" which is unhelpful.
Once you've done this, you can import all the contacts. Then I suggest saving them on your PC in SPB format (via Kies, little save icon in the top left of Contacts | PC tab) so that you never need to do this again! You can edit and tweak the contacts in Kies then, before finally transferring them to your Samsung Galaxy.
