A leading group of mobile device hackers have released a software update that allows iPhone and iPad users to circumvent content controls using the latest version of Apple s iOS operating system. The Redsn0w jailbreak works on iPhone 3GS devices using an updated boot ROM, as well as iPhone 4, iPad and iPod touch 2G, 3G and 4G devices. It builds on earlier jailbreak code, dubbed limera1n, which was created by a mobile hacker using the handle Geohot.
