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.
The following instructions will help you jailbreak iOS 4.1 on iPhone 4 and iPhone 3GS using GreenPois0n.
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 (instructions here), 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 the link given below.
Step 2: Connect your iPhone via USB to your computer and click on “Prepare to Jailbreak (DFU)” as seen in the screenshot below.
Step 3: Now follow the following onscreen instructions:
- Press and hold the sleep button for 2 seconds
- Continue holding sleep; press and hold home for 10 seconds.
- 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:
Unlock for iOS 4.1 (Old Baseband) 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. Step by step instructions for unlocking can be found here.
