"For all devices running iOS 8.0 and later versions, Apple will no longer be performing iOS data extractions as the data sought will be encrypted and Apple will not possess the encryption key.
For iOS devices running iOS versions earlier than iOS 8.0, upon receipt of a valid search warrant issued upon a showing of probable cause, Apple can extract certain categories of active data from passcode locked iOS devices. Specifically, the user generated active files on an iOS device that are contained in Apple’s native apps and for which the data is not encrypted using the passcode (“user generated active files”), can be extracted and provided to law enforcement on external media.
Apple can perform this data extraction process on iOS devices running iOS 4 through iOS 7. Please note the only categories of user generated active files that can be provided to law enforcement, pursuant to a valid search warrant, are: SMS, iMessage, MMS, photos, videos, contacts, audio recording, and call history. Apple cannot provide: email, calendar entries, or any third-party app data."
I can see how you read this. I read it another way. There was encryption on the device, but it was circumvented in iOS4 through iOS7 (so called "active data") so that law enforcement could access it (over snailmail). The implication is that 'active data' persists longer than the alivetime of the device.
"It is further ordered that, to the extent that data on the Device is encrypted, Apple may provide a copy of the encrypted data to law enforcement but Apple is not required to attempt to decrypt, or otherwise enable law enforcement's attempts to access any encrypted data."
I can see how you read this. I read it another way. Many of the CALEA programs allow businesses to 'volunteer' data or to volunteer to decrypt information. They've been bullied into doing this. Apple says that it will take a stand, but I don't have very much trust in them because them ultimately is a board of directors chasing profits.
"iCloud only stores content for the services that the subscriber has elected to maintain in the account while the subscriber’s account remains active. Apple does not retain deleted content once it is cleared from Apple’s servers. iCloud content may include stored photos, documents, contacts, calendars, bookmarks and iOS device backups. iOS device backups may include photos and videos in the users’ camera roll, device settings, app data, iMessage, SMS, and MMS messages and voicemail. iCloud content may be provided in response to a search warrant issued upon a showing of probable cause."
iCloud data syncs by default. That is, they've added data encryption to singular devices but placed the data by default into their cloud, where they offer decryption for law enforcement.
