Release notes
What changed
Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.
Apple’s archived index and advisory place iPhone OS 3.1.3 on February 2, 2010. A same-day Macworld report preserves ordinary fixes for iPhone 3GS battery-level accuracy, third-party application launch failures, and crashes involving the Japanese Kana keyboard.[1][2][3]
Apple’s primary advisory separately confirms five security items across crafted audio, TIFF images, recovery-mode USB handling, FTP directory parsing, and remote media loading in HTML mail. The ordinary changes remain attributed to contemporaneous journalism because they are absent from Apple’s retained advisory.[4][5]
