For reasons that we cannot begin to imagine, known hacker and security guru Stefan Esser (i0n1c) has tweeted that he will do an untethered jailbreak for iOS 4.3.5. Yeah, not iOS 5, but iOS 4.3.5. We don't get it, either.
Dedicated jailbreakers that haven't wanted to ditch their untethered jailbreaks are likely still on iOS 4.3.3 (it was the last firmware that was accompanied with an untether, ala JailbreakMe). Then there's the possibility of a few users who truly hate iOS 5 and haven't updated for that reason. Whatever the intention, i0n1c seems to think that we need an untether for 4.3.5.
The latest version of RedSn0w 0.9.8b was recently released by the Dev Team, and it includes two key components.
The first component, is compatibility with the iPad 1 iOS 5 beta 6 IPSW. Apparently, Apple updated this IPSW without altering its version or filename, so this latest version of RedSn0w features compatibility with both the original and updated files...
If you may recall, with the release of the long awaited JailbreakMe 3.0 for iOS 4.3.3, literally 10 days later Apple patched the clever PDF exploit in iOS 4.3.4. The security exploit could be triggered by viewing a maliciously crafted PDF file which may lead to an unexpected application termination or arbitrary code execution.
While the main reason Apple patched the exploit was to stop the use of JailbreakMe, it can also be a security concern. A few days later, Apple released another iOS software update, iOS 4.3.5. Apple released this update to patch the certificate validation vulnerability.
If you love customizing your iDevice to the fullest, you've probably already jailbroken, unless you didn't update by accident or purchase your iDevice after Apple stopped signing iOS 4.3.3. Unfortunately, while not updating to the latest software may preserve your jailbreak, you may also be at risk from the same vulnerability...
Apple recently released iOS 4.3.5 to patch a few security vulnerabilities, and RedSn0w has already been confirmed to offer a tethered jailbreak on Apple's latest firmware.
If you're on an iPhone 4 with an unlocked baseband, jailbreaking iOS 4.3.5 with RedSn0w will not preserve your baseband. Luckily, a custom build of PwnageTool has been released to fix that problem.
Following the release of iOS 4.3.5 this morning, we issued our usual warning about staying away from the latest firmware so that you don't lose your jailbreak or unlock.
This warning is still in effect for those who don't want a tethered jailbreak. For the rest of you who don't mind plugging your iDevice in your computer every time you have to reboot, the word on the street is that RedSn0w can jailbreak iOS 4.3.5...
With the release of iOS 4.3.5 and 4.3.10 earlier today, I think it would be safe to remind you to stay away from the "update" button if you care about your jailbreak or unlock.
If you run a stock iPhone or iPad then go ahead and update to the latest firmware. But if, like most iDB readers, you heavily rely on a jailbreak/unlock, make sure you do not update...
Apple has released iOS 4.3.5 for the iPhone, iPod touch and iPad. This update is now available in iTunes and fixes an apparent security vulnerability with certificate validation.
iOS 4.3.5 can be applied to your iDevice by updating your software in iTunes.
