Apple has released a new version of iBooks. The new version is iBooks 2.1. It’s a redesign to support the new iPad Retina Display and adds a feature that lets page numbers correspond to the printed editions. This only works on some titles, but obviously the feature will be spreading to more and publications.
With new update, now you can search for a page number and jump to it with a single tap. You can use your finger as a highlighter when swiping over text.
Changes in the new version of Find My iPhone are mainly to support the iPad Retina Display. Many bugs have been fixed and new stability enhancements are there.
