Apple wants to make sure you’re in touch with all the new stuff it’s put out there in the last couple of days and have done so by releasing brand new iBook user guides for your edification.
There are three mobile guides:
These guides cover both hardware and software, so if you don’t need a refresher course on your phone or iPad, you can skip to the sexy parts that cover new items like Apple Music, new iBook enhancements (who knew?) and a host of new features.
Launching iTunes on your desktop, search for “ios 8.4 user guide,” and download the ones for your devices. The next time you sync your device with iTunes, the user guide will appear in iBooks.
Go ahead and have a look. They’re free.
