First, thank you very much for this code

Yahoo Error:

Exception at /contact-import/

Cannot retrieve a contact list

----After Debugging Issue found which is guid gets None value---

guid is None,
get_guid_url = 'http://social.yahooapis.com/v1/me/guid?format=json'
gives 404 in response message......
so that
get_contacts_url = 'http://social.yahooapis.com/v1/user/None/contacts?format=json'
This above url cause the Exception ..... because of None...

First, thank you very much for this code. It works great for Google and Yahoo. But attempting to use this on Hotmail doesn't work as of 8/27/2012.

When attempting to auth with Hotmail, I receive a message like, " is making an insecure request to access your information. Windows Live does not allow information to be shared with this type of request."
