I found this forum when I looked for solutions to iBook 2.1.1 update problems. I hve the original iPad, minimum gigs (20, I believe). It's been great for travelling ovesees. About a month agao, I got a prompt to update to iBook 2.1.1 It has been stuck in "installing" every since and the icon is grayed out. Connecting it to the main computer and syncing it has not helped.
