KIES won't help to get the contacts from a sony phone though!
You'll need the sony PC suite to get the contacts off the sony phone by syncing it with the windows address book and then use KIES to sync the address book back to the Samsung phone.
RATTERIS - Cant move sim as its different network.
JOEDUNE & CHUCKFICKENS - will look in to this way, but having trouble getting my phone to show contacts in the PC Suite, only shows one contact every time i run it.
Thanks.
