Release notes

What changed

Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.

Contemporaneous reporting preserved four items from the iOS 4.3.1 update notice: a sporadic graphics problem on the fourth-generation iPod touch, activation and connectivity trouble on certain cellular networks, image flicker with the Apple Digital AV Adapter on some televisions, and authentication failures involving some enterprise web services.[1]

The same report dates the public release to March 25, 2011. Apple’s surviving first-party security corpus independently establishes iOS 4.3.1 as the predecessor covered by the iOS 4.3.2 advisory, but Apple’s archived security index does not preserve a separate 4.3.1 entry. The structured notes therefore rely on the cited contemporary report rather than presenting that material as a surviving Apple web page.[2][3][4]
