Windows Users:(If you have mozilla firefox or chrome, use that over Internet explorer! If you download the iPhone firmware (IPSW) through Internet explorer, watch this video how to turn firmware from .zip to .ipsw, we need it as a .ipsw!)
Mac Users: Make sure you turn off "Open safe files after downloading" by going to Safari (upper left hand corner) then preferences, then uncheck the "Open safe files after downloading".
Jailbreak Verizon iPhone 4 4.2.9 firmware for free with redsn0w, works on Mac and Windows. It will work on any desktop or laptop. This is a tethered jailbreak, tethered means everytime you need to turn your phone back on, you will have to rerun the jailbreak, this is only temporary, follow kittyra1n's facebook and twitter to be updated as soon as an untethered jailbreak (only have to jailbreak once) comes out. While technically Apple considers jailbreaking voiding the one year warranty, all you have to do is restore in iTunes and your iPod Touch will be back in warranty, this goes the same for insurance. If you are on Verizon wireless, this will not affect your existing wireless service. This jailbreak is similar to limera1n, sn0wbreeze, and greenpois0n. You will be downloading the Verizon iPhone 4.2.9 firmware file, you can download it using mozilla firefox or google chrome it is quite large and depending on your isp (internet service provider) and your internet connection speed, it could take a while.
Download and save Redsn0w
Download and save Verizon iPhone 4 Firmware 4.2.9 IPSW
(You should download the firmware through firefox or Google Chrome, if you download it through Internet Explorer, change the extension from .zip to .ipsw, if you download the firmware through Safari, before you start the download go to Safari in the upper left hand corner, click "Preferences" and uncheck "Open safe files after downloading")
If you downloaded it through Internet Explorer, heres how to change the .zip into .ipsw
If you are on Windows Vista or Windows 7, right click redsn0w and click "Run as Administator", if you are using XP, or a Mac, you do not need to do this step, just open it normally.
IF your computer asks are you sure you want to open this file, say Yes
Once redsn0w is open, click browse, we are going to browse for the other file we downloaded, the Verizon iPhone 4 4.2.9 firmware.
Find and choose the Verizon iPhone 4 4.2.9 IPSW firmware, it should be in your downloads folder, but it could be somewhere else, if redsn0w isnt recognizing it, you need to download the ipsw again through firefox, and choose that one.
Once redsn0w successfully recognizes the Verizon iPhone 4 4.2.9 IPSW, press next
Choose "Install Cydia", I don't recommend choosing anything else unless you know what they mean.
Now make sure your iPhone is plugged in, if it is, turn it off. Before you press next, you will have to put your Verizon iPhone 4 into a special mode, a mode called DFU mode, essentially you hold the power button for 3 seconds, once you see the Apple logo come up, hold down the home button at the same time as you're holding the top button for 10 seconds, after 10 seconds, let go off the top button but keep holding the home button for 10 more seconds!Your Verizon iPhone 4 screen should now be blank, if it is blank, press next, if it isn't try DFU mode again, if you need help watch this video.
Ignore any messages from iTunes, DO NOT RESTORE IT NOW, now that your Verizon iPhone 4 is in DFU mode, press next on redsn0w, this will jailbreak your iPhone, leave it plugged in until it finishes.
Since this is a tethered jailbreak, your Verizon iPhone 4 might not boot up right after the jailbreak, just run redsn0w the same as you did before, except this time just choose "boot tethered", you will have to do this everytime your turn your phone back on until the untethered version comes out. Remember to follow kittyra1n's facebook and twitter.
If you ran into any errors, such as stuck on uploading ram disk, check this video on how to fix it, then run redsn0w again.
