Release notes
What changed
Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.
MacRumors reported the public release of iPhone OS 3.1.2 on October 8, 2009 and preserved three items from the update notice: wake-from-sleep failures, cellular service interruptions that could persist until restart, and occasional crashes during video streaming.[1]
No surviving first-party Apple feature page or dated security-index entry for 3.1.2 was found in the reviewed source set. The local audited date is retained and the three ordinary fixes are labeled as contemporaneous journalism rather than first-party confirmation; no security or undocumented-change claim is inferred.[2][3]
