I take iTunes reviews very seriously. If you have any issues downloading the iBook, please contact me at Ben@A320guide.com or at http://www.a320guide.com/contact. I am always there to help and we always find a solution :-) The common downloading error is a lack of memory. The iBook requires slightly over 1 Gb for download. That's a lot of memory - I know - but there are a lot of pictures, videos and interactive diagrams. It's worth it! Not enough memory will cause a download error message at the end.
Did you purchase this A320 iBook recently? Please take the time to go on iTunes, find the iBook and post a review. This is always greatly appreciated! And as always, all updates are free! More content will soon come!
