--> Apple releases iOS 6.1.1 for iPhone 4S users with 3G issues (Updated) | Ars TechnicaApple has now released the iOS 6.1.1 update mentioned in our original writeup. The update is specifically for the iPhone 4S and "fixes an issue that could impact cellular performance and reliability for iPhone 4S." This is most likely to address the 3G issues experienced by some users, though it doesn't sound like iOS 6.1.1 does anything to improve battery life as of yet.
Does not really matter for iPads, I guess, so it's not critical to upgrade, but does anyone know if the jailbreak still works if you do decide to update?
