Hello guys, please forgive me for being a noob. I am completely new to jailbreaking. In fact, I just got my first iPhone 4 from Verizon last week and I am planning to jailbreak iPhone 4 on my Windows. It’s already running on iOS 4.2.9 firmware on Windows. Where can I download Redsn0w 0.9.8b3 for my iPhone 4 4.2.9? Is the new Redsn0w supports Windows users? How to use Redsn0w 0.9.8b3 on Windows? Your help will be greatly appreciated.

Well, before you jailbreak your Verizon CDMA iPhone 4, you should be note that this new version of Redsn0w offers tethered jailbreak method, which means you have to connect your iPhone 4 to your PC and boot it into tethered jailbroken state every time you restart or turn it off. This is due o the fact that the Cupertino, California-based Apple have patched the untethered jailbreak exploit that was used to jailbreak iOS 4.3.1 up to iOS 4.3.3. Now, to jailbreak iOS 4.2.9, all you have to do is follow the simple instructions posted below:
Step 1: Download and install the latest version of iTunes on your PC.
Step 2: Download iOS 4.2.9 IPSW file for your CDMA iPhone 4 from this link.
Step 3: Make sure that your device is running on iOS 4.2.9 (or iOS 4.3.4 for GSM iPhone users). Launch iTunes and update or restore to iOS 4.3.4 using the standard IPSW file. But make sure that you are holding down the SHIFT (Windows) or ALT (Mac) key so you can browse for the 4.2.9 IPSW.
Step 4: Now, launch the download Redsn0w jailbreak tool and point it to iOS 4.2.9 firmware file. Redsn0w will automatically identify the firmware and it will inform you once done.
Step 5: Click on Next and this should take to a window where you will be able to select which components of the jailbreak you’d like to install. Of course, you will need to Install Cydia in order to access numerous jailbreak apps and tweaks. You can also install other options, but only if you know their functions. Click Next once done.
Step 6: As instructed by Redsn0w, make sure that your device is both plugged in and turned off before you click on the Next button
Step 7: Now you have to put your iPhone into DFU mode, just follow the on-screen instructions.
Step 8: Redsns0w will detect your iPhone in DFU mode once you have successfully put your iPhone DFU mode. If it does, then all you have to do is wait for the tool to jailbreak your iOS device till it completes the jailbreaking process.
That’s it! You now have a tethered jailbroken iPhone on iOS 4.2.9. To tethered boot your iPhone, just simply connect your device into your PC then launch Redsn0w and choose Just boot tethered right now instead of Install Cydia option.
