iOS 6.1.1 doesn't break evasi0n jailbreak, at least not yet
The first beta of iOS 6.1.1 doesn't block the popular new jailbreak, though Apple could be saving that feature for the final version.
The evasi0n jailbreak is so far safe from the clutches of iOS 6.1.1.
Released by Apple to developers yesterday, the first beta of the iOS update tweaks Apple's Maps app for Japanese users but otherwise is light on changes. And as tweeted by iOS hacker pod2g, the beta does not block the evasi0n jailbreak, as some feared it might. However, he cautioned people who want to install the evasi0n jailbreak to stick with iOS 6.1.
6.1.1 beta (10B311) does not fix the jailbreak. It'll probably happen in a future revision. Don't upgrade though, evasi0n won't let you jb.
Evasi0n is able to jailbreak every iOS 6 and 6.1 device currently on the market, including the iPhone 5, the iPad Mini, the fourth-generation iPad, and the fifth-generation iPod Touch. The tool itself also is considered simple to use, certainly in comparison with other jailbreak methods.
Apple is likely to try to block evasi0n with the final release of iOS 6.1.1.
The jailbreak has proven extremely popular, used at least 1.7 million times in just the first day after its release on Monday. The tool was initially scheduled to debut on Sunday. And that's when Apple tweaked its online jailbreak warning page.
The page cautions potential jailbreakers of the various hazards of the practice, including instability, security vulnerabilities, shortened battery life, unreliable voice and data, disruption of services, and the inability to apply future software updates.
Apple also warns that jailbreaking violates the end-user license, and as such, the company may deny service to any device running "unauthorized software."
