Yes. It's optional, but most users use an iCloud account that sync their address book, calendar, etc. Just like Microsoft and Google.

- bdash 13y agoAs far as I'm aware, iCloud accounts aren't required for push notifications. The push notification system identifies devices by an opaque token that isn't tied to any user-identifiable information. Edit: The Apple Push Notification Service documentation at https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html#//apple_ref/doc/uid/TP40008194-CH100-SW9 https://developer.apple.com/library/ios/documentation/Networ... talks about the architecture and seems to match my recollection.
