Last week a tethered jailbreak was released for iOS 6 running on the iPhone 4, iPhone 3GS, and iPod touch 4th generation. While it was great to have a jailbreak so soon, the jailbreak didn't include any GUI tools like Cydia, only SSH and afc2 support were added.
Fortunately, now that we have SSH access, we can transfer and install pretty much anything on our jailbroken iOS 6 devices, including Cydia.
Check inside for the full video tutorial that shows you how to install Cydia on iOS 6 beta...
