There are so many people talking about others with a un-tethered JB for iOS 5. Valuable information: If the Dev Team or GeoHotz didn't release it then it is probably 100% FAKE!!
When a REAL version is released it will be on every iphone/ipad site on the net not some YouTube video.
We are all waiting on a Un-Tethered JB so we are all still looking and getting our hopes up too easy. I am just relaxing and waiting it will be worth the wait (I hope) !
