I Phone 5 Advantage & Disadvantage ...

I phone 5 good: The iPhone 5 adds everything we wanted in the iPhone 4S: 4G LTE, a longer, larger screen, free turn-by-turn navigation, and a faster A6 processor. Plus, its top-to-bottom redesign is sharp, slim, and feather-light.

I phone 5 bad: Apple Maps feels unfinished and buggy; Sprint and Verizon models can't use voice and data simultaneously. The smaller connector renders current accessories unusable without an adapter. There's no NFC, and the screen size pales in comparison to jumbo Android models.

Bottom line: The iPhone 5 completely rebuilds the iPhone on a framework of new features and design, addressing its major previous shortcomings. It's absolutely the best iPhone to date, and it easily secures its place in the top tier of the smartphone universe.

 that covers all bases, here it is. Just like the MacBook is to the world of laptops, the new iPhone is one of the top three, if not the best-designed, smartphone around. It's better in all the important ways.

Editors' note: We are continuing to update this review with additional observations and test results. Among the latest additions (October 4, 2012) are the inclusion of 4G LTE speed tests (see "4G LTE: Faster, at last" section); detailed comparisons to camera quality between the iPhone and rival smartphones (see "The camera" section); and detailed battery test results for both video playback and talk time (see "Battery" section).

What's different?Look at our review of last year's iPhone 4S, where we said, "Even without 4G and a giant screen, this phone's smart(ass) voice assistant, Siri, the benefits of iOS 5, and its spectacular camera make it a top choice for anyone ready to upgrade."  Like every year in the iPhone's life cycle, a handful of important new features take the spotlight. This time, 4G, screen size, and redesign step to the top.

You've gotten the full rundown already, most likely, on the various ins and outs of this phone, or if you haven't, I'll tell you about them below in greater detail. Here's what I noticed right away, and what made the biggest impression on me.
