This latest jailbreak solution is being called the “Spirit” jailbreak. For newer iPhones (and iPod Touches), the Spirit jailbreak allows you to complete the jailbreak hack without having to connect the device to your computer. Previously, users would have to “tether” their new iPad to a computer to finish the boot process. Spirit now makes it possible to jailbreak all iPads and iPhones, regardless of manufacturing date, without the need to tether.
What’s bigger, though, is that the Spirit jailbreak works on iPhone OS 3.1.2 – the very iPhone OS build that powers the new Apple iPad. That’s a big deal, because the iPhone OS 3.1.2 can now be hacked to run third-party software like Multifl0w. Rather than wait for Apple to loose iPhone OS 4.0 on all iPads later this year, this jailbreak will allow you to hack your way to multi-tasking.
Multifl0w allows the user to continue running an iPad app in the background by opening the app and holding down the “Home” button, just like another multi-tasking app known as “Backgrounder.” But, it’s Multifl0w’s window-based multi-tasking interface that really sets it apart from the crowd. Double-clicking the Home button brings up a gallery of iPad app windows, allowing the user to flick through various running apps and interact with them at will. Closing an app is as simple as holding down the Home button on an open app.
Keep in mind that Spirit is a jailbreak only. It won’t unlock your iPhone for use with other carriers. Also, make sure to read the warnings on using Spirit here from the Dev Team.
