Welcome Verizon iPhone owners! I've been writing tutorials for over three years now for AT&T
iPhones and I'm excited to be writing the first tutorial for the iPhone's official second carrier in
the United States. Please read this tutorial before attempting to do anything. Understand what you
are doing, follow what I've documented, and everything should
go exactly as described.
There is a lot to learn in this tutorial and I'll present it as simply as I can.
Thanks go out to the Chronic Dev Team for providing the greenpois0n jailbreaking program for free!
You can visit their website here,
their blog here,
and their Twitter here
more about the team and even ask them questions. Keep in mind they created this jailbreak, I am
merely a person documenting its use.
If you also decided against spending the extra $20 per month for the Personal Hotspot option,
you can still tether. Check out my tutorial on this
after you've jailbroken.
There is one known problem after performing this jailbreak. You will be unable to open any
books with DRM protection using the iBooks program.
Here's my iPhone 4 already on 4.2.6 firmware and 1.0.05 modem firmware. You do not need to restore
your iPhone to continue following these instructions. However, if you have firmware 4.2.5
installed, then this procedure may not work. If this is the case, sync your iPhone with iTunes
first so you don't lose any data before restoring.
Warning: Apple releases new firmware throughout the year. Do not rush to
update your firmware (even if you receive a text message from Verizon) if you value your jailbreak!
Generally speaking, it can take weeks for a jailbreak to be released in response to new firmwares
being released. While you may be able to restore to older (and Apple unapproved) firmware, you
should still not rush into this.
Note: I always blur out my serial number, Wi-Fi address, Bluetooth address and MEID for privacy
reasons. No one needs to know this information but me.
Double click the .zip to decompress
it. A folder will appear. Open the folder and drag the greenpois0n.app icon into your Applications
folder on your Mac. This program has been updated frquently in the last week, so your version
number may be higher than the ones depicted below. This is okay.
I recommend downloading 4.2.6 firmware from Apple here:
You don't need this firmware for this tutorial, however if you want to restore to this firmware
at some point in the future and Apple is no longer approving its use, you will have the option
of going back to it. It saves time to have this file stored locally. More on this later.
If you just opened the box on your iPhone, then turn it on and connect it to iTunes first. You'll
see the welcome screen. Just follow through the various screens to set up your iPhone.
When you are done you'll see this screen. Note: I blur out my serial number and phone number
for privacy reasons. You'll notice the capacity in your "other" category will increase by a few
hundred megabytes as part of the jailbreak process.
Don't forget to dial *228 to finish setting upyour iPhone with Verizon (only if you've never done
this before with this phone). You will receive a confirmation voice message while on the call and
a pop up message.
Ensure iTunes is closed. Launch greenpois0n. Make sure your iPhone is plugged into your Mac. I had
to turn my iPhone off for this to work. If you have a firewall that monitors outbound Internet
connections then you will have to approve greenpois0n for access as it needs to download a payload
as part of the jailbreak process. If you have to approve the outbound connection, you may have
to repeat this process from the beginning (I did) as it may fail inititally.
Click the Jailbreak button.
You'll have three seconds to press and hold the on/off (sleep/wake) button.
While holding the on/off button, press and hold the home button.
Release the on/off button, but keep holding the home button.
A blue status bar will zip by a few times. You can release the home button.
A couple lines of text will appear at the top of the screen. Then code will scroll and fill up the
Click the Complete button and the program will close. You are jailbroken at this point, but this
are a couple more things to do.
The code will pause for about one minute and then continue scrolling slower. A skull logo will
appear on the iPhone and change to an Apple. You may also see a spinning wheel under the skull.
Note: this new animation logo makes the phone boot slower. If you want to remove the skull logo
then install OpenSSH (read
) onto the iPhone,
then go to the /usr/bin directory and delete (or rename) the file named "animate".
Ensure you have an Internet connection then press the Loader icon. Press Cydia.
Press Install Cydia. It could take some time to download so be patient. The delay is caused by
new jailbreaks and new iPhones being released. When it finishes installing press the home button
(the iPhone may reboot).
You should now see the Cydia application icon. Launch the Loader application again. Press the
Press the Remove Loader.app button. Press the home button and the iPhone will respring. The Loader
icon should now be gone.
