Transfer phonebook from Motorola V360 to SE K810i

I just purchased a Sony Ericsson K810i to replace the Motorola V360. I've had the V360 for over two years but not its falling apart. Here I will list out the steps to transfer the phonebook from the V360 to the K810i using Ubuntu Linux 7.10 (Gutsy) via USB cable.

1. Create a folder to store the phonebook
mkdir ~/phone.v360

2. In V360,
Settings ->Connectivity ->Sync ->USB Settings ->Data/Fax Connection

3. in Linux
Applications ->Accessories ->KMobile Tools
Choose Phonebook ->All contacts from phone ->Refresh
(If there are many phone numbers, then have to wait longer)

cp ~/.kde/share/apps/kmobiletools/kmobiletools.vcf ~/phone.v360

4. In SE K810i
Plug in the USB cable
Select Phone mode
Choose Settings ->Contacts ->Options ->Advanced ->Backup to M.S.

5. in Linux copy the phonebook from the phone to the Linux
cd ~/phone.v360
cp "/media/PHONE CARD/System/PIM/PB_Backup.vcf" .

6. if there are same names in PB_Backup.vcf and kmobiletoos.vcf then remove them. Otherwise merge the two files. Of course if PB_Backup.vcf is blank the overwrite it with the kmobiletools.vcf file. I take it that the phonebook in the phone is to be backed up and then renamed to PB_Backup.vcf.original

mv PB_Backup.vcf PB_Backup.vcf.original
mv kmobiletools.vcf PB_Backup.vcf
mv PB_Backup.vcf "/media/PHONE CARD/System/PIM"

7. In SE K810i
Unmount PHONE CARD media
Unplug the USB cable.
Select Phone mode
Choose Settings ->Contacts ->New Contact ->Options ->Advanced ->Restore from M.S.

When prompted:
Delete old contacts before new contacts are added?

Choose No

The K810i now have all the phone numbers. Check it out.
