Apple has released iOS 6.1.1 for iPhone 4S devices, presumably fixing the 3G issues that carriers warned their customers about with the iOS 6.1 update. The update, which is specific to the iPhone 4S, comes with a build number of 10B145. It weighs in at a relatively paltry 23MB.
A beta of iOS 6.1.1 was released in the middle of last week carrying a build number of 10B311 — it’s likely the upgrade released today was an urgent bug fix and the prior iOS 6.1.1 beta sent to developers will become iOS 6.1.2.
