This is step-by-step instructions on how to perform tethered jailbreak of your iPhone 4 on iOS 4.3.5 firmware using RedSn0w 0.9.8b7b for Windows.
Tethered jailbreak means that each time you restart your device you will need to connect it to a computer and run redsn0w.
If you have other device, here are links to our RedSn0w 0.9.8b7b iOS 4.3.5 jailbreak tutorials:
UPDATE: Please, consider reading our Jailbreak & Unlock FAQ , especially if you have questions or troubles.
Please think first, before you do something.
If you have iOS 4.3.3 firmware - do an untethered jailbreak using one of our tutorials .
If you need carrier unlock - do not update firmware, use PwnageTool or Sn0wBreeze to create custom firmware!
Create a folder on your desktop called Pwnage
Download RedSn0w version 0.9.8b7b or higher from here . Save it in the Pwnage folder. Likewise, download iPhone 4 firmware iOS 4.3.5:
Extract the redsn0w executable from the RedSn0w zip file into the same folder.
Connect your iPhone to the computer and launch iTunes.
Select your iPhone from the list of devices on the left. Create a backup by right-clicking on iPhone name in Devices (iTunes left pane) and choosing Back Up.
If you are already on iOS 4.3.5 you can now skip to step three.
Now hold down Option (Mac) or Shift (Windows) key and click the Restore button.
Navigate to the Pwnage folder on your desktop and select the 4.3.5 firmware ipsw. Click the Open button to continue.
Once iTunes has finished updating your iPhone to the desired firmware open the Pwnage folder on your desktop and launch the redsn0w application from the redsn0w folder we extracted earlier.
On Windows Vista or Windows 7 right click the executable and set it to run as administrator in Windows Vista/XP compatibility mode.
Once RedSn0w opens click the Browse button
Select the 4.3.5 firmware ipsw we placed in the Pwnage folder on our desktop then click Open.
Once the firmware has been verified click the Next button to continue.
RedSn0w will now prepare the jailbreak data
From this window you can select the jailbreak options you would like.
Make sure Cydia is selected.
Click the Next button to continue
Please plug your iPhone into the computer and make sure its OFF then click the Next button
RedSn0w will now guide you through the steps to get into DFU mode.
1. Hold down Power button for 2 seconds.
2. Without releasing Power button, hold down both the Home button and the Power button for 10 seconds.
3. Release the Power button and continue holding the Home button until RedSn0w detects the device.
If you have problems try again. Here is a video showing this Step 10:
iPhone will reboot
RedSn0w will then begin uploading the new RAM Disk and Kernel.
Once this is complete you will be notified that RedSn0w is done. Click the Finish button.
Once RedSn0w has finished you will need to boot tethered your iPhone. You will need to do it everytime you restart.
Rerun RedSn0w and this time select Just boot tethered right now from the list of options instead of installing Cydia.
When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.
Run Cydia. Let it do all the necessary updates.
To have access to the root file system of your iPhone (via file managers like iFunBox or iPhone Explorer) install application called afc2add in Cydia.
Do not forget to change your default password  if you've installed openssh.
