merry christmas to me, I upgraded my fully functioning ipad 2 to iOS 6. What a mistake. Most of my apps do not work. It no longer recognizes epub file types. My biggest pleasure was using the iPad to read books. This pleasure is now permanently lost as apple does not provide a path to revert to the previous os. My beautiful ipad is now useful only as a browser. What a piece of ****. Unhappy to the max. I dare not press the reset button or connect it to my iMac as I might lose everything on it . Planning a trip to the genius bar but expecting huge disappointment. Recent upgrades to my imac produced similar results. You'd think I would have learned. So , Please, don't upgrade. Steve Jobs would never let this happen.
