For Seniors: Navigate a Book on Your iPhone 4S
Your iPhone 4S can double as an e-reader if you download iBooks or other reader apps. Navigating through a book is much the same on your iPhone as on any e-reader.
Tap iBooks and, if your Library (the bookshelf) isn’t already displayed, tap the Library button.
Tap a book to open it. The book opens to its title page or the last spot you read.
Take any of these actions to navigate the book:
To go to the book’s Table of Contents: Tap the Table of Contents button at the top of the page and then tap the name of a chapter to go to it.
To turn to the next page: Place your finger anywhere along the right edge of the page and flick to the left.
To turn to the preceding page: Place your finger anywhere on the left edge of a page and flick to the right.
To move to another page in the book: Tap and drag the slider at the bottom of the page to the right or left.
To return to the Library to view another book at any time, tap the Library button. If the button isn’t visible, tap anywhere on the page, and the button and other tools appear.
