Missing Your Cydia App After Jailbreaking iOS 4.2.1 with GreenPois0n?

 

Unless you’ve been living under a rock for the past few hours, you know that the long awaited GreenPois0n untethered jailbreak for iOS 4.2.1 was finally released.

Maybe it’s just me, but I always seem to run into some sort of problem with missing or broken Cydia installations after a successful jailbreak.
To fix this issue I was able to install RedSn0w 0.9.6 on top of my GreenPois0n jailbreak with no ill results. By doing this you will still retain your untethered jailbreak, while gaining the necessary Cydia icon.
