Following the release of an iOS 6.1.1 beta for developers, henceforth officially since February 11, 2013, iOS 6.1.1 for the iPhone 4S is released to address issues with 3G performance, issues reported mainly in Europe.
iPhone 4S users can now update OTA (Over the Air) by going
to Settings > General > Software Update. The update is small; only 23Mb, you can therefore, use cellular data to update, also through iTunes by plugging your iPhone on your computer.
Finally, iOS 6.1.1 is compatible with jailbreak tool Evasi0n; the tool will be updated to recognize the new iOS 6 version.
