Jailbroken iOS 6? Here's How You Can Get The Cydia App On Your iDevice

If you're rocking a jailbroken iOS 6-powered iDevice, you'll know that the iPhone Dev-Team's jailbreak method doesn't install the Cydia app. This is because the jailbreak is designed for developers only, who wish to test their tweaks and apps against the new mobile operating system before it's released in fall. However, as iDownloadBlog notes, it is indeed possible to install Cydia on a jailbroken iOS 6-powered iDevice after jailbreaking, via the method outlined below.
1 - You need to have installed iOS 6 beta 1 on your developer-registered iDevice, and also to have jailbroken it using the iPhone Dev-Team's recently released redsn0w 0.9.13dev1 software. Once you've done this, boot tethered your iDevice using the software.
2 - SSH into your iDevice, and execute the following command: "wget -q -O /tmp/cyinstall.sh http://wyndrepo.googlecode.com/files/cyinstall.sh && chmod 755 /tmp/cyinstall.sh && /tmp/cyinstall.sh" (without the quotation marks).
3 - Your iDevice should re-spring, and the glorious Cydia app will appear on your Home screen.
It's a relatively simple method - just remember that most jailbreak tweaks and apps won't have been updated for iOS 6, and that you'll probably run into some compatibility problems. Besides putting together the original post, iDownloadBlog also uploaded a video of the process for jailbreakers to check out, which we've included below. Good luck!
