The iOS 4 update was released just yesterday and iOS users all over the world downloaded it and are going all gaga over the multitasking capabilities it carries. However, the update has also caused some undesirable changes to data relating to many apps, data which is supposed to be stored on the iPhone storage permanently.
Thomas Baekdal at Baekdal made a post talking about the loss of all books on his iPhone as a result of the update. This happened to the iBook app in particular. Baekdal saw some anomalies with the app starting with it being empty in place of a test book present in the earlier cases. Next, when he tried to get those books back with a download, all the options he got led him to a “buy” option.
Baekdal made a further experiment and tried to sync on his iPad which worked perfectly. The problem seems to be with his iPhone only, even particularly with the iBook app.
That has led him to conclude that this is a problem with the iBook app and it is advised that you switch your reading habits to something more reliable and specialized, something like the Amazon Kindle.
Did any of you have any problems after updating to the iOS 4? I would be glad to hear from you.
