iPhone 5S and iPhone 5C Portable Genius

Very helpful though I have to add my own simplified how-to's b/c often the most basic things are either assumed or buried someplace. That said, the book is easy to read and contains tons of info. Definitely worth the money.

Clear, reasonably basic, and comprehensive (so far). The book is a 'genius', but I'm not so I have to do a LOT of re-reading to fully understand how to use/understand certain features. The book is a good place to start, but I am curious if a "Dummies" book would have been any better.

Well written and easy to understand especially for people who have not used a Smart phone in the past. Highly recommend to get it. It has helped me to learn fast how to use my new Smart Phone.

I am so new at what and how to use the iPhone that it i very informative. But sometimes I get overwhelmed with the information/functions of the phone that I have to put it down and come back latter.

After purchasing my new 5S phone, I needed some specific guidance on how to perform certain functions. This handy book is my new go to resource. I use it all the time and it's packed with great information.

Although I ordered "iPhone 5S and iPhone 5C Portable Genius", Amazon shipped me "iPhone for Dummies 7th addition", which included the 5S, 5C, and iOS7. I originally wanted to order this "iPhone for Dummies" book, but the 5S (7th addition) was not available at the time of order.

Clear and easily understood by one who was unfamiliar with the iPhones. Text is understandable and the illustrations are clear and helpful. Since these iPhones and their OS are more complex than first appears a systematic tutorial fills a real need. Likely not needed by those with a good understanding of previous iPhone models and OS.

Written very well. covers it all. Have gotten a number of very good tips already. I am very happy with this book. I know it will help me learn all the features of the iPhone.

A good book, clearly written, that answers most queries you may have. Many tips and functions I did not know about until I read this book.

Good Info time and battery saving

Good informative book using pictures to show what to do on phone. Took almost a month to receive book

Firstly:I have had to purchase a separate user handbook to learn how to operate, what is, a very sophisticated piece of equipment. Secondly: I am finding it difficult to set up e-mail internet connections. Thirdy: my handbook states that iphone 5S is equipped with finger print security although my iphone does not have that facility. I have tried to contact Apple who require me to download my iphone details to them but, because I cannot set up internet email connections, I am unable to do so. All in all, an expensive connundrum!

I am a new Iphone user and I was hoping for a book that would have simple, illustrated steps to working with the iphone. It just all seems to be geared for people that have used iphones of all types before. It is not basic enough for the new user.
