The new patch allows users to jailbreak iOS 6.1.3 on Pre-A5 iDevices: iPhone 4 (GSM and CMDA models), iPhone 3GS, and iPad touch 4th generation. The patch still requires tethering for full functionality after boot, and newer Apple devices (iPhone 5, iPhone 4S, iPad Mini, iPad touch 5, iPad 4 with A6X chip and Retina Display, iPad 3 and iPad 2) can't be jailbroken for now.
The semi-untethered jailbreak was developed just a day after Apple released the patch. The new hack came in the form of a video tutorial posted by YouTube account iCrackUriDevice, which details how to beat the new upgrade with a relatively easy RedSn0w workaround).
Here's the iOS 6.1.3 semi-untethered jailbreak tutorial video:
The summary for the iOS 6.1.3 semi-untethered jailbreak tutorial video also features links to iCrackUriDevice's Twitter account, Facebook page and a link to further RedSn0w instructions from besttechinfo.com.
"Is there going to be an [iOS 6.1.3] untethered jailbreak soon? Because I'll only upgrade for FULLY untethered," asked MagicRecon123 in the comments section.
"Let's just put it this way, STAY on iOS 6.1.2 or lower :D," was iCrackUriDevice's pessimistic response.
When asked by another iDevice owner when a universal iOS 6.1.3 untethered jailbreak would be available, iCrackUriDevice hinted that we may have to wait until Apple launches it's next-gen operating system.
"Unfortunately, it'll be a while. I wouldn't be surprised if there isn't another Untethered Jailbreak until iOS 7!" he wrote.
So what's the difference between an iOS 6.1.3 untethered jailbreak and the current semi-untethered version? Evasi0n notes on their website that "it is possible to install what's known as a semi Tethered or a Semi UnTethered jailbreak on iOS 6.1.3 after completing this tutorial. This will allow the iPhone or iPod touch to reboot without the assistance of a computer with limited functionality. If you've previously jailbroken using a tethered version of redsn0w, jailbreaking 6.1.3 should be easy for you."
Here's their step-by-step tutorial on how to unlocked iOS 6.1.3 with a semi-untethered jailbreak:
Step 1: Download Redsn0w from our download section, which is linked below, to ensure that you have an authentic version of the tool.
Step 2: Once Redsnow has been successfully downloaded, if you're on Windows, right click the utility, set compatibility mode to Windows XP Service Pack 2 and grant the program administrative privileges. Mac users needn't worry about compatibility, as practically all versions of OS X can use the utility immediately after downloading it.
Step 3: Run Redsn0w and click Extras, followed by Select IPSW. In the pop-up window, simply point Redsnow at the iOS 6.0 IPSW, not 6.1.3. After the firmware has been successfully identified, click the Back button to return to the main Redsn0w menu.
Step 4: Click the Jailbreak button, ensure that the option to, Install Cydia was checked by default and continue to the next screen. At this point, Redsn0w suggests turning your device off to enter DFU mode, although it's possible to bypass this stage of the jailbreak entirely by entering DFU mode ahead of time.
Step 5: To enter Device Firmware Update mode, simply connect your iPhone or iPod touch via a standard 30-pin USB cable, press and hold both the home and power buttons for a total of ten seconds. Once ten seconds has passed, release the power button and continue to hold the home button for an additional ten to fifteen seconds.
Step 6: If you've entered DFU mode correctly, Redsnow will automatically proceed. Simply wait for the process to complete and for your jailbroken device to reboot, after it has, you'll need to boot Tethered.
It's good to hear that an iOS 6.1.3 untethered jailbreak for iPhones (or at least semi-untethered) has arrived so quickly. The mood online within the jailbreaking community yesterday when Apple unleashed their latest patch bordered on apocalyptic, with community leaders urging jailbreakers to avoid the update at all costs:
"IOS 6.1.3 is out. Jailbreakers stay away! There's no coming back to 6.1.2 JB even if you saved blobs (except iPhone4 and ipt4g)," tweeted jailbreaking expert MuscleNerd @MuscleNerd.
Meanwhile, the online tech media' reports wre equally gloomy concerning an iOS 6.1.3 untethered jailbreak. CNET ran a story with the headline "Evasi0n jailbreak thawrted by iOS 6.1.3," and continued to explain that "Apple has finally managed to contina the Evasi0n jailbreak in their lede.
The articles notes that although the Apple update was allegedly designed to patch a lock screen security bug, but also effectively renders the popular Evasi0n tool dead on arrival:
But the update also patched several holes that Evasi0n exploited to perform an untethered jailbreak on all iOS devices, including the latest iPhone, iPad, and iPod Touch. People who upgrade to iOS 6.1.3 will no longer be able to use Evasi0n to jailbreak their devices. And once on 6.1.3, newer Apple devices cannot be downgraded to a previous iOS version.
CNET also notes that the lack of an iOS 6.1.3 untethered jailbreak is no coincidence (though we already knew that). It turns out Apple actually credited the jailbreaks for revealing four gaping security holes that the new update has patched up, according to the Cupertino-based company's website.
An iOS 6.1.3 untethered jailbreak may be out of site for most iPhone and iPad owners for the time being, but on the bright side there's nothing making you upgrade against your will and overall Evasi0n has been a resounding success with around 18 million downloads in just 43 days, according to Forbes.
Here's a bit of context on the foiled iOS 6.1.3 untethered jailbreak from Forbes:
Compared to some previous jailbreaks, Apple took its time in patching evasi0n. By contrast, the company took only nine days to fix the bugs exploited by Jailbreakme 3. But that tool allowed anyone to jailbreak his or her phone or tablet simply by visiting a website, creating the risk that it would be repurposed by malicious hackers to perform "drive-by downloads" of malware onto Apple devices that visited an infected website. Evasi0n, on the other hand, requires a USB connection between the device being jailbroken and a PC, vastly reducing the risk that it could be used for malicious purposes.
The popular website spoke to David Wang, one of the four hackers who developed Evasi0n, and he notes in the interview that he still hasn't given up hope for an iOS 6.1.3 untethered jailbreak. He explains that one iOS 6 security remains unpatched, and hints that he's got a treasure trove of untouched iOS bugs waiting in his pocket to be unleashed.
In the end though, an iOS 6.1.3 untethered jailbreak may be just a dream.
"We'll probably wait until the next major release," says Wang.
