Apple has started emailing customers who bought the Steve Jobs biography e-book from the iBookstore, asking them to delete their copy and redownload a new version. Since the launch of the highly anticipated biography, customers who purchased an e-book version from Apple’s iBookstore have been complaining of formatting issues, forcing Apple to update the digital book and contact customers.

The news comes in a report published by Macworld UK. The emails, sent from Apple’s “iTunesStoreSupport@apple.com” account, thank customers for purchasing the e-book, noting that a new version is available to download “at no charge” and explaining how this can be done.

If your version of the e-book hasn’t been working properly, delete the biography in iBooks, sign out of the iBookstore and then sign back in, and redownload the book via the “Purchased” tab in the iBookstore. This should solve the aforementioned formatting issues, which involved pictures not loading correctly and text not looking quite right. No changes have been made to the e-book’s content.

You can download “Steve Jobs” by Walter Isaacson from the iBookstore for $16.99. The e-book can be read in the iBooks app on an iPhone, iPad or iPod touch.
