First of all, greenpois0n RC5 is available for both Windows and Mac OS X and you can find jailbreak tutorials here: Windows, Mac OS X.
Okay, now let's move on to the questions and answers. The order is random and the questions have already been asked by several users in the comments, I answered them, but I think it is good to make an article visible to everyone.
Can I use greenpois0n on iOS 4.1?
No, it only works with iOS 4.2.1.
Can I use greenpois0n over jailbreak tethered with redsn0w?
Yes, greenpois0n works without problems.
Do I lose the installed applications if I jailbreak with greenpois0n?
No, if you jailbreak with greenpois0n over redsn0w you don't lose anything.
Can I use greenpois0n if I have an untethered jailbreak with redsn0w 0.9.7 aka Jailbreak Monte?
No, you have to restore before using greenpois0n.
Can I use greenpois0n if I have baseband 06.15.00? Does greenpois0n update baseband?
Yes, it doesn't matter what baseband you have, greenpois0n does not affect the baseband.
I have iPhone 4, can I update to iOS 4.2.1 without baseband update?
Yes, it's coming this tutorial strictly and you will be able to do it without problems.
The Loader application does not appear after the jailbreak. How do I install Cydia?
Try to reset the terminal, this is the method recommended by the Chronic Dev Team for solving problems. If it doesn't work, then install Cydia with redsn0w. Open redsn0w, select the appropriate ipsw, choose Install Cydia and that's it. This process does not affect the jailbreak.
Does the phone activate greenpois0n?
No, greenpois0n does NOT activate the phone, so if you have an iPhone coded in a foreign network and you don't have the operator's card on which it is coded, then you have to jailbreak with redsn0w first and jailbreak with greenpois0n afterwards. Details can be found in the tutorial for greenpois0n published today. If you have a neverlocked/factory unlocked terminal, you can activate it with any card.
If I update to iOS 4.2.1, can I decode the terminal?
NO, if you update to iOS 4.2.1 you lose the possibility of decoding! The exception is iPhone 3G/3GS terminals that have iPad baseband.
Does greenpois0n decode the iPhone?
No, greenpois0n does not decode the iPhone.
I get error 1013/1015 after restoring to iOS 4.2.1.
In your case, enter the terminal in DFU Mode with the steps from the greenpois0n tutorial, then jailbreak.
Does greenpois0n solve the GPS problem?
No, the problem with the GPS is due to the baseband 06.15.00 which can only be solved by a baseband downgrade.
Does greenpois0n affect battery life or signal quality?
My signal does not fluctuate, it is not weaker, everything is ok for now. I haven't noticed any decrease in battery autonomy, so for now everything is ok with me.
If you have other problems, please specify them in the comments and I will include them in the article. Please share this article with others to enlighten the world about the possibility of using this new jailbreak solution.
