iPhone users with early access to iOS 4 have been reporting that Apple began pushing out the iPhone version of the iBooks reader on Friday. The app gives iPhone users access to iBookstore publications, just like the iPad.
Like the iPad version of iBooks, the iPhone app includes a copy of Winnie the Pooh.
So far, it looks like users aren’t having any luck installing iBooks on the iPhone 3G, so this may be an app that requires at least an iPhone 3GS, according to Engadget. iPhone and iPod touch owners that aren’t running iOS 4 currently don’t have access to iBooks, although Apple has promised a June release.
