Yes! Jailbreak iOS 5.0.1 on iPhone 3GS, iPhone 4, iPad -- Untethered
Good news, everyone! Now you can jailbreak your iPhone 3GS, iPhone 4, or iPad, with iOS 5.0.1 and reboot untethered. At last! Find out how, in The Long View...
Thanks to the sterling efforts of pod2g, you can now jailbreak your A4-based iDevice, without being encumbered by the dreaded tether. (If a jailbreak is said to be tethered, it means that the jailbreak is undone if you reboot the phone -- in other words, you must connect your phone to your PC or Mac to properly boot it. An untethered jailbreak is the gold standard, because you don't need to muck about with any of that nonsense.)
But first, here are some top tips, learned from bitter experience. Ignore them at your peril:
- Before doing anything, back up your iPhone in iTunes.
- Make sure you stop iTunes from automatically updating itself -- A long-term fear is that Apple may introduce anti-jailbreaking code into a future iTunes update, stop that software from auto-updating.
- Make sure you stop iTunes from automatically updating your iPhone -- iOS updates will almost always undo a jailbreak and you may find that new updates aren't jailbreakable (at least, for a few days or weeks).
- Plug your iPhone directly into a USB socket on your Mac or PC's case -- do not use a USB hub.
- Unplug as many other other USB devices as you possibly can.
- Use a genuine Apple USB cable, or a 3rd party cable that you know to be of good quality -- some cheapo cables can appear to work fine for regular syncing and charging, but fail in subtle ways when jailbreaking.
- Be patient -- some of the steps involved in jailbreaking an iPhone take longer than you might think. If it appears to have hung, it probably hasn't. Set aside plenty of time to do the jailbreak; the last thing you want to do is interrupt it mid-process.
As ever, take care; read and understand all the caveats, both here and in the linked pages -- lest you create an expensive brick. Neither I, nor Computerworld are responsible for anything you choose to do with your iDevice -- only you are.
Tool downloads and instructions are at the usual place: the Dev-Team blog. At present, the instructions are a bit sketchy, so I wouldn't recommend that inexperienced jailbreakers try this just yet. I'll post again when I think the situation's settled down.
For now, if you're already rocking an iOS 5.0.1 tethered jailbreak, you can install a package from Cydia, called Corona. Hop over to your Cydia app, search for Corona, and install it. The Chronic Dev Team has more here.
