I installed "http://www.redmondpie.com/enable-video-mirroring-and-multitasking-gestures-on-ipad-1-running-ios-5-without-jailbreaking-video/" on my iPad1 per the instructions--went w/o a hitch. The mirroring does seem to work. Oddly, HBOGo doesn't mirror for me, though. ABC works fine and the few apps I tried did too. The mirroring isn't explicit in the download instructions but work fine anyway. BTW I am not jailbroken.
