With the advent of iOS 4.0, Apple just released iBooks 1.1 and my my, the best reader app just got better! Featuring syncing of places, bookmarks, notes between devices. This is HUGE! It works seamlessly – any changes made on your iPhone, or your iPad are immediately synced to your iTunes account OTA (over the air), and the next time you open the iBooks app in iPad or iPhone, you can see the changes reflected from the other device, as well as continue from where you left off. Flawless implementation, and my hat is off to the iBooks team.
