It was all fine until yesterday, all of a sudden I've been getting:
The remote server returned an error: (400) Bad Request
I'm afraid Apple has done some change to the service this week but
don't know where to look for the new specs.
Is anyone aware of the changes?
Here's the request to https://contacts.icloud.com:
