Any idea how to bulk transfer contacts from Google/Gmail to iCloud

Wondering as well.

This blog has a guide: http://geekboys.tumblr.com/

I assume you'd need to turn off any Google syncing you're currently using and start from scratch in Address Book, so that there won't be duplicates.

There seems to be an option for importing Vcards but its greyed out , but i believe that vcards is individual contacts only ,

move gmail contacts, agenda and email to iCloud

This is how you switch from Gmail to iCloud on your Mac and leave your gmail intact in case you ever want to go back. Description how to move your contact, agenda and all your email to iCloud:

What is mentioned above works only for macs. If you use a PC, then you have to do it in another way.

The way I did it was as follows:

- Open iTunes, and sync contacts via iTunes with your gmail. Do not add your gmail account from your phone, do that later. Simply put your gmail account and let iTunes sync and don't forget to click apply!

- Your contacts are now all in your iPhone, synced with your gmail account. You need to untick the sync contact in iTunes again, it will ask you if you if you want to keep contacts or delete them. Obviously you click keep. Click apply. This is the only way your iPhone will keep gmail contacts without deleting them. If you stop syncing via your iphone, your phone will delete all contacts without giving you the option to keep them.

- Now you basically have all your contacts stored in your iPhone, without having gmail sync'd to them. Setup your iCloud account, then and only then do you turn on syncing contacts on iCloud (if you had iClouds setup before the mentioned steps.)

Enjoy.
