I was looking for an easy way to get all the phone numbers from my Facebook contacts into my G1 today, since I lost all my numbers when my previous phone died this summer.

Finally found a great solution that worked like a charm. Brad Fitzpatrick, founder of LiveJournal, wrote both a tool to merge contacts into your Google contacts, and a GreaseMonkey script to extract the contacts from your Facebook phonebook.

You can find it here: AddressBooker & exporting my Facebook Phonebook.

Here’s what you do:

1. First, make sure you’re using Firefox with GreaseMonkey installed.
2. Go to your Facebook phone book. Log into Facebook, click Friends at the top, then click Phonebook on the left.
3. Then in the Firefox menu, go to Tools->GreaseMonkey->User Script Commands->Export Facebook Phonebook
4. Log into AddressBooker with your Google account, and follow the instructions.

After a few steps and a few minutes, I now have 97 phone numbers from my Facebook friend in my Google contacts, which is updated to my G1 phone.
