Apple’s new mobile firmware, the iOS 6 beta 1 has been released for all registered Developers. Moreover, its leaked build has also been available via several mirror download links as well as torrent networks. The news is really a hit and being a high wave because it is a major update. Now, as usual, iPhone Dev Team has also pushed out newer version of RedSn0w with ability to jailbreak iOS 6 B1.
Unlike many other previous versions of RedSn0w which usually also has “B1, B2, and so on” on its name. This one has “Dev” word within its last name.
So meet the RedSn0w 0.9.13dev1, a Developer build 1 of Redsnow that is available for both Mac OS X and Windows. Meant for developers only, so you better stay away from iOS 6 B1 as well as its jailbreak tool. The Dev team stated that there are many components may not work including Apple’s default apps. Hence, once jailbroken, you’ll found no Cydia app installed.
Personally I suggest to avoid this one unless you are know and sure about what you are going to do.
iPhone 4, iPhone 3GS, and iPod touch 4G
The Jailbreaking Process
Now launch RedSn0w app. On Windows 7 or 8, make sure you run it as Admin (right-click >> Run As Administrator).
Click on the “Extras” button not the “Jailbreak” one.
Now you’ll need to manually specify the iOS 6 .IPSW file by clicking “Select IPSW” button on RedSn0w.
Now locate the .IPSW file you’ve been extracted.
Once RedSn0w identified the .IPSW file, click OK then hit the “Back” button to return to previous page.
Now click on the “Jailbreak” button.
On the next page, you’ll see several options and you’ll also notice that Cydia is currently not available yet for iOS 6. Tick the “Install SSH” then hit the “Next” button to proceed.
Now follow on-screen instruction to put your iPhone / iPod Touch to DFU Mode. Once done, click on the “Next” button.
Now sit tight and wait for RedSn0w to do its job.
Once done, your iDevice will run jailbroken iOS 6 b1 in jailbroken tethered state. That’s all. Please do remember that it is a tethered mode which requires you to boot into tethered mode each time your iPhone/iPod is turned off.
