We’ve released an emergency iOS 6 bug fix for the Mumble iOS client today — Mumble for iOS 1.1.1.
It works around a compatibility issue with iOS 6 that caused users to be silent when transmitting audio. A few other crash bugs have also been fixed in the 1.1.1 release.
Along with that, the new version of the app uses the latest version of MumbleKit.
As always, it’s available on the App Store. And don’t forget — if you enjoy the app, please spread the word, and remember to rate it in the App Store.
