Release notes
Editorial synthesis with inline references and a source ledger when citations are available.
Apple’s dated records place iPhone OS 3.1 on September 9, 2009. Apple’s launch material ties it to home-screen organization in iTunes, more selective media and photo syncing, Genius Mixes and Genius for Apps, direct ringtone purchases, MobileMe remote lock, and anti-phishing protection.[1][2][3]
The matching security advisory covers crafted audio, Exchange passcode policy, deleted mail in Spotlight, recovery-mode access, SMS resilience, password display, credential leakage, cross-site scripting, code execution, and deceptive internationalized URLs. Claims specific to iPod touch are not generalized to every iPhone.[4][5]
