As expected, fast. Flow exploit used by jailbreaking tool greenpois0n, redsn0w and attack the boot rom limera1n IOS devices, which are outside the Apple bits that can be changed in the software. Thus, no issue can be resolved without new hardware, which means that, for now, all IOS devices are capable of being jailbroken using the same method.
Our own Erica Sadun reported dubious results of the initial jailbreak dev build IOS 4.2, but this has been completed, and the iPhone Dev Team reported that they redsn0w tool can now jailbreak all IOS devices 4.2.1.
There are some caveats, however.
First, if you use the tool ultrasn0w to unlock your phone (so you can use it with any operator), then you have two problems. One, the tool itself does not work on IOS 4.2; two, if you allow iTunes to update to a newer version of the software baseband 4.2, it probably will not work anymore on your phone. If you rely on the operator to open, or if you think you are ever likely to depend on it, you always have to stay away from the IOS update to one of the dev team supplies a tool to create custom IPSW file. This will give you all the good thick phone from 4.2.1 but let the software, the old baseband unlockable in tempat.Kedua, on newer devices (specifically iPhone 4, 3GS newer model iPhone, iPod touch 3G and beyond, and IPAD ) this is called a tethered jailbreak. This means that every time you reboot your device, you must have physically connected to your Mac or PC with jailbreak software is running, if not, it will boot up again without a jailbreak in place. Obviously this can be both a warning serius.Mengharapkan disorders should be treated in time, although there are, of course, there is no guarantee for how long.

To the Dev-Team has noted that IOS jailbreak 4.2.1 for older devices (running on bootrom old) is ready for your device.
This is caused by the latest RedSn0w build, 0.9.6b3, which hit the web-wave last week in order to hack the GM build of the latest IOS.
"Because our original combination pwnage2 exploit, the exploit arm7_go, 24kpwn, and limera1n, your device jailbreakable same as usual", read a statement in Website Dev-Team. "You reap the full benefits of the 4.2.1 jailbreak untethered."
Newer devices tend to view the jailbreak untethered (so you do not need to be hooking it up to your PC every time you run out of battery to reset) in the near future, with @ Comex currently working on it
Now, as always, we warn you that jailbreaking iDevice you need some knowledge about the inner workings so that you do not.Dan while the practice is legal, do not expect too genius to help if you take a jailbroken device is inconvenient to the Apple Store.
