After a long delay stretched back to before the holiday season, Apple today released iOS 13.3.1 developer beta 2, along with the equivalent pre-release version of iPadOS.

These are a bug-fix updates, meant to remove small problems introduced by software updates for iPhone and iPad in December.

Apple has acknowledged a connectivity issue with iPhone XR units connected to O2, the second-largest carrier in the United Kingdom.

Many users have been unable to make or receive calls or text messages. They have also been stuck without a reliable data connection, which renders most apps unusable without Wi-Fi.

Apple today made its first iOS 13.3.1 and macOS 10.15.3 betas available to developers.

The minor updates don’t have patch notes yet. But they likely fix a serious flaw in Communication Limits, which can allow messages to be received from unauthorized contacts, among other bugs.

New betas are also available for HomePod, iPad, and Apple TV.
