iOS 5.1.1 Jailbreak Hacked Already

Apple's new iOS 5.1.1 may only have been available for iPhone, iPad and iPod touch users for a few hours, but already there's a jailbreak solution for installing unofficial apps, as long as you have the right device. The iPhone Dev Team's MuscleNerd has confirmed that those with devices not based on the Apple A5 chipset – which means the iPad 2 and new iPad, as long as the iPhone 4S – can use the previously released redsn0w jailbreaking tool.

You can find downloads for redsn0w here, in versions for Mac and Windows. There are instructions for running the jailbreak process here.

Those with an iPad 2, new iPad or iPhone 4S, however, should stay away from iOS 5.1.1. Upgrading now could put you another step down the line from a jailbreak whenever one is developed for A5-based hardware.

The new iOS release improves the reliability of HDR photography, smooths out switches between 2G and 3G networks on the new iPad, and addresses some AirPlay video streaming bugs. There's also improved reliability around synchronizing bookmarks in Safari and the Reading List, as well as finessing to App Store purchases.
