The simplest way would have been using the contacts' app integrated export/import functionality:
- on the "source device": open contacts, open menu, select "Export/Import", export to SDCard. This will export your entire contact list (including photos) to a
.vcf
file in the root of your sdcard. - copy the resulting
*.vcf
file to the "target device" - on the target device: open contacts, menu, export/import, import from SD. Chose the file.
- Done.
