Apple has just released iOS 6.1.1 (build 10B145) for iPhone 4S.
The update fixes the 3G connectivity issues that was affecting iPhone 4S users, which we had reported over the weekend.
From the release notes:
This update fixes an issue that could impact cellular performance and reliability for iPhone 4S.
It is currently available via OTA. It is 23MB in size.
Jailbreakers should avoid upgrading your iOS device to iOS 6.1.1, until the evad3rs dev team release a new version of evasi0n jailbreak for it. Jailbreakers should also take a backup of the SHSB blobs for iOS 6.1 using TinyUmbrella before Apple stops signing iOS 6.1 firmware file, if you haven’t jailbroken your iOS device with evasi0n yet.
It’s quite strange that Apple has released an update only for iPhone 4S, as iOS 6.1.1 beta that was seeded last week was available for all iOS devices.
If you were facing the 3G connectivity issues, then let me know if things have improved after installing the update.
You download iOS 6.1.1 for iPhone 4S directly from here.
planetbeing of evad3rs dev team has confirmed that evasi0n jailbreak still works with iOS 6.1.1. They will be releasing an update to support iOS 6.1.1 shortly.
