Installation went fine, things seemed to be working, left the iPad connected overnight to my MacPro and this morning the iPad won't wake up, no signs of life whatsoever. I have tried: - Holding wake/sleep button > 10 secs. - Holding wake/sleep & Home buttons> 10 secs. - Plugging to USB, plugging to charger directly. Nada. - Did the stuff in http://support.apple.com/kb/HT1808 Next, I guess, is the Genius at the Apple store. I'm guessing this is a fluke or coincidence as I haven't seen anyone else reporting this same issue but there's always the first one.
