So if you have an Apple TV like I do and have missed the ability to stream from Safari, the AirVideo app or StreamToMe is worth a download right now!
AirVideoEnabler enables video streaming to Apple TV's using AirPlay from any application, including Safari. Normally, AirPlay Video is restricted to the YouTube app. This tweak is now available in the Cydia Store
Apple changed the orientation lock button and made it a mute switch. Then, they put the orientation lock in the multitasking tray, which you can access with a single swipe to the right.
NoMute for iPad, available for free in Cydia now, makes the mute switch button an orientation lock button again.
