Jailbreak iOs 4.1 ipt2 now supported!!!(Windows/Mac/Linux)

Chronic Dev Team has finally released GreenPois0n to the world. You can use it to jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPod touch 4G / 3G and iPad. Support for iPod touch 2G and Apple TV will be added soon.

Here is official description...

greenpois0n only works on firmware 4.1, so (only if you have an iPhone 4!) if you are on a lower firmware make sure you use TinyUmbrella to preserve your baseband.


Initially, this will be a Windows-only release. This is due to some technical complications that we soon hope to correct. We apologize for any inconvenience.

Thanks to geohot for the bootrom USB exploit. We have opted to use that instead of SHAtter for the sake of exploit presevation.

This release of greenpois0n supports:
- iPhone 4
- iPhone 3G S
- iPod touch (4th Generation)
- iPod touch (3rd Generation)
- iPad

Soon there will be another release, adding things like support for:
- Apple TV (2nd Generation)
- iPod touch (2nd Generation)


PS:
From my dear friend Dr. Adelante' description..




The following instructions will help you jailbreak iOS 4.1:

NOTE: If you rely on an unlock, do not update to iOS 4.1 yet as doing so will upgrade your baseband, making it impossible for now to unlock. Either use TinyUmbrella to update to iOS 4.1 without update baseband, or wait for PwnageTool which will help you cook custom firmware files for iOS 4.1 without the upgraded baseband.

Step 1: Download GreenPois0n from HERE.

Step 2: Connect your iPhone via USB to your computer and click on “Prepare to Jailbreak (DFU)”



Step 3: Now follow the following onscreen instructions:

A. Press and hold the sleep button for 2 seconds

B.*Continue holding sleep; press and hold home for 10 seconds.

C.*Release sleep button; continue holding home for 15 seconds.

Step 4: Your device is now ready for jailbreak. Click on “Jailbreak” to inject the exploit.



Step 5: Your iPhone, iPad or iPod touch should now be successfully jailbroken on iOS 4.1 !

Step 6: Now start “Loader” found on the homescreen and install Cydia.



JAILBREAK SUCCESS!!!


There is currently no way to unlock your iPhone on the latest 05.14.02 / 2.10.04 basebands. If you have managed to preserve your baseband while upgrading to iOS 4.1 using TinyUmbrella, you can use the existing version of Ultrasn0w to unlock your iPhone on iOS 4.1.


Now, there are currently two jailbreak available but using the same exploit..

The two methods are confirmed by me to be working on my iphone 3Gs new bootrom..

IF No Cydia Icon After Jailbreaking with greenpois0n?

The greenpois0n jailbreak has proved to be somewhat buggy for some users, including us. Fortunately, we’ve been able to navigate around a few of those bugs with a little bit of tinkering.

One of the biggest reported problems is the lack of a Cydia icon on your springboard following a successful jailbreak. Look inside for a step-by-step guide on how to add Cydia back to your springboard!

Step 1: Jailbreak using greenpois0n.

Step 2: Download either iFunBox or iPhoneBrowser, and plug in your iPhone. This will allow you to navigate your phone’s directory structure if the jailbreak was indeed successful.

Step 3: Navigate to /var/mobile/Library/Caches directory, delete ‘com.apple.mobile.installation.plist’ and reboot.

Step 4: When you reboot you should see a Loader icon on your springboard. Access Loader to download Cydia, and reboot.

Step 5: Once you reboot you should see both Cydia and Loader icons! You can uninstall Loader if you want
