Apple has released yet another update to it's iOS, also known as iPhone OS. iOS 4.3.5 (or iOS 4.2.10 to Verizon iPhone 4 users) was released earlier tonight.
Since the launch of JailbreakMe.com 3.0, Apple rushed to update iOS to patch the vulnerability, releasing iOS 4.3.4 rather quickly. However, they got something wrong as this update fixes "a critical security issue". It seems there was a "certificate validation" vulnerability, which has forced Apple to release iOS 4.3.5 to fix this. It is looking like they wanted to release it before hackers could use the vulnerability for malicious reasons, or to stop a jailbreak exploit before it is found.
Those of you with an iDevice on 4.3.3 (and jailbroken) STAY AS FAR AWAY AS YOU CAN FROM THIS UPDATE - if you update you will lose your jailbreak. For those of you on iOS 4.3.4 however, update as fast as you can.
Along with this update it has been reported that it is still jailbreakable (although tethered) via redsn0w 0.9.8, here's how (credit to You must login or register to view this content. on redmondpie.com)

Step 1: Download iOS 4.3.5 and iOS 4.3.4 (required by this version of Redsn0w) firmware file for your device from the links given at the end.
Step 2: Download Redsn0w 0.9.8b4 for Windows or Mac. Also make sure you are running the latest version of iTunes, which is version 10.4.
Step 3: Now start Redsn0w, browse for the iOS 4.3.4 firmware file (NOT the 4.3.5) that you downloaded in Step 1 and point it towards Redsn0w.
Step 4: Once Redsn0w is done recognizing the firmware file, click Next and there you’ll be taken to a new window. Simply check the “Install Cydia” box as shown below and leave other options as it is for now. Once done, click Next.
Step 5: On this screen, Redsn0w will instruct you to power down your device and plug it in to your computer. Follow the onscreen instructions and then click Next to continue.
Step 6: On this screen you will have to put your device in DFU mode with a combination of the Power button and the Home button for a certain amount of time, simply follow the onscreen instructions on how to do so. The combination is usually like this:
If you performed the above mentioned steps correctly, then your device should be in DFU mode.
Step 7: Redsn0w will now jailbreak your device, don’t do anything weird at this point, just let Redsn0w finish. We would recommend that you don’t do anything with your PC or Mac at all during the process. Sitting idle and waiting for the process to end on its own is much advised.
Step 2: Download Redsn0w 0.9.8b4 for Windows or Mac. Also make sure you are running the latest version of iTunes, which is version 10.4.
Step 3: Now start Redsn0w, browse for the iOS 4.3.4 firmware file (NOT the 4.3.5) that you downloaded in Step 1 and point it towards Redsn0w.
Step 4: Once Redsn0w is done recognizing the firmware file, click Next and there you’ll be taken to a new window. Simply check the “Install Cydia” box as shown below and leave other options as it is for now. Once done, click Next.
Step 5: On this screen, Redsn0w will instruct you to power down your device and plug it in to your computer. Follow the onscreen instructions and then click Next to continue.
Step 6: On this screen you will have to put your device in DFU mode with a combination of the Power button and the Home button for a certain amount of time, simply follow the onscreen instructions on how to do so. The combination is usually like this:
- Hold down Power button for 5 seconds.
- Now without releasing the Power button, hold down the Home button simultaneously with the Power button for 10 seconds.
- Let go of the Power button but keep on holding the Home button for another 15 seconds.
If you performed the above mentioned steps correctly, then your device should be in DFU mode.
Step 7: Redsn0w will now jailbreak your device, don’t do anything weird at this point, just let Redsn0w finish. We would recommend that you don’t do anything with your PC or Mac at all during the process. Sitting idle and waiting for the process to end on its own is much advised.
The jailbreak works on all iDevices except for iPad 2.
