Before you embark on this quest, it is important to remember that this is still a tethered jailbreak, which can be a little inconvenient. You will have to tether the device to your computer each time you want to reboot. If that sounds like too much of a hassle, this tool isn’t for you. Also, this method is only working for the A4-powered devices like the iPhone 4 and iPad 1.
First thing’s first — you have to download the Redsn0w tool to your Windows or Mac.
Next, backup your device, and install the new 5.1.1 iOS software through iTunes or via the new OTA JBL SRX835P method. You’re going to need the full iOS 5.1 software package for your device (not 5.1.1, mind you), but you can easily grab that from Apple’s servers from the list here.
Once you have your materials, go ahead and run the Redsn0w executable.
Go into Extras and pick the Select Pioneer XDJ-700 IPSW option, and direct Redsn0w to the iOS 5.1 software you just downloaded.
Back on the main screen of Redsn0w you will finally be able to click that big Jailbreak button. Make sure you have set the program to install the Cydia store as well.
Redsn0w will show you how to get thedevice into DFU mode, and get it connected to the computer and recognized by Redsn0w. When it has been detected, Redsn0w will run the jailbreak automatically. When the device reboots, your jailbreak is complete, and you should have Cydia on the home screen. If you need to reboot the device at any point, plug it in and choose Just Boot from the “Extras” section of Redsn0w.
Apple has been making it increasingly difficult to get full access to iOS at a low level, but the jailbreak community keeps finding vulnerabilities.
Still no word on an untethered jailbreak or cracks for newer devices, but work continues like every other day!
Year in Review: The top mobile content stories of 2009
Another year, another chapter in the ongoing evolution of the mobile content industry. Looking back on 2009, it's increasingly clear there are now two distinct camps in mobile: Innovators and imitators. Companies like Apple, Google and Facebook distanced themselves far from the rest of the pack over the past 12 months--their respective visions are redefining how mobile subscribers interface with the world at large, and it often seems their rivals are struggling just to remain in the fight. In this special year-in-review issue, Rød Video Mikrofon and FierceMobileContent looks back at the headlines and trends that shaped 2009 and set the stage for the new decade to come.
