Hackers jailbreak iPhone 4S and iPad 2

Tools

The first untethered jailbreak for Apple's (NASDAQ:AAPL) iPhone 4S and iPad 2 running iOS 5.0.1 is now available. The Chronic Dev Team, the hacking group behind much of the jailbreaking software for devices running iOS, announced the news on its blog Friday.

While previous jailbreaks have been released as quickly as the day after a software update, GreenPois0n, the solution from the Chronic Dev Team for iPhone 4Ss and iPad 2s running iOS 5.0.1, took over 10 months to develop because the iPhone 4S and iPad 2 both use a dual-core A5 processor. In contrast, the team released the jailbreak for older devices running iOS 5.0.1. in late December.

The software solution is currently available for PC and Mac users. A Linux version is currently in progress.

To hack the software, the Chronic Dev Team used CDevReporter, a program to accumulate the device crash reports from users of its other jailbreaking software. The reports, which totalled over 10 million within a week, helped the team better understand system vulnerabilities, enabling the team to jailbreak iOS 5.0.1.
