Greenpois0n, next generation jailbreak tool for IOS 4.1 is going to available in wild on coming Sunday, 10th of the October at 10:10:10 PM. Greenpois0n is able to hacktivate your phone which is important for people who don’t have official iPhone SIM card to activate.
Things you should know about Greenpois0n:
1. Greenpois0n jailbreak supports iPhone 4, iPad, iPod touch 4G and most probably Apple TV. No support for iPhone 3GS, 3G and iPod touch 2G, 3G.
2. iPhone 4 unlockers should wait for Dev team to release pwnage tool (which is supposed to release very short after Greenpoison).
3. Once again! the ultrasn0w carrier unlock won’t work on 4.1’s baseband (and you can’t go back to earlier basebands) if you want to preserve your iPhone 4 unlock stay away from restore/update to stock IPSW.
4. Yes Greenpois0n is untethered jailbreak so your device does not require you to reboot with a jailbreak.
5. We will be posting tutorials on how to jailbreak your specific device as soon as the jailbreak is available.
