Read previously sent and received SMS messages via iCloud

Question

I know it's possible because of the existence of APIs and applications that do this.

As far as I can tell, however, the relevant APIs are undocumented.

How can I read previously sent and received SMS messages via iCloud?

Answer 1

InflatableDonkey is an open source project that downloads iCloud backups.

SMS messages are stored in target/backups/<icloud_username>/<hash>/<date_str>/HomeDomain/Library/SMS/sms.db, which is an SQLite3 database.
