Prepaid or postpaid?: The fight for your cell phone dollars (Smartphones Unlocked)

This article originally published 11/11/2012 and was updated most recently on 3/25/2013.

Now that T-Mobile has smashed into the center of the no-contract wireless game, the tussle for your business between the contract and no-contract carrier model is even more urgent.

There's no question that the prepaid model is designed to save you money over a two-year contract agreement, but how much do you really gain by going prepaid, and what might you lose from the subscriber experience?

For the sake of comparison, I'm going to break down the cost of ownership over a … Read more

FCC has phone-unlock ban on its radar

The Federal Communications Commission might eventually investigate whether it should be illegal for consumers to unlock their mobile phones.

Speaking to TechCrunch in an interview published yesterday, FCC chairman Julius Genachowski said that the ban is "something that we will look at at the FCC to see if we can and should enable consumers to use unlocked phones." He went on to tell TechCrunch that the "ban raises competition concerns; it raises innovation concerns."

The U.S. in January made it illegal for consumers to unlock mobile phones -- a relatively common practice among unhappy carrier … Read more

Camera megapixels: Why more isn't always better (Smartphones Unlocked)

Note: This article originally published May 6, 2012 and updated on February 13, 2013.

Increasingly, the 8-megapixel smartphones camera standard you thought you knew will ratchet up to 13 megapixels for high-end phones.

In many products -- like this past January's Pantech Discover (12.6 megapixels), last October's LG Optimus G for Sprint (13 megapixels), and even last year's HTC Titan II (16 megapixels) -- we're already there.

And no, I won't forget to mention last February's Nokia 808 PureView, a 41-megapixel Mobile World Congress 2012 stunner that CNET camera editor Josh Goldman says … Read more

How to sell your phone for cash (Smartphones Unlocked)

In last month's Smartphones Unlocked, I shared what happens to your smartphone when it ceases to be yours.

Although I listed resources for getting rid of your phone (and took a poll of what CNET readers usually do with their old handsets,) it's high time I offered up some tips for how to go about selling your phone...or any other consumer electronic, for that matter.

Don't count on a Hawaiian vacation for your efforts, but depending on how much you hoard or how savvy you sell, the dollars could really add up.

Your smartphone's secret afterlife (Smartphones Unlocked)

A blue mat, a fine-tipped screwdriver, and a dozen itty bitty screws. This is Titus Green's workspace, set within a warehouse that processes 2 million pounds of unwanted electronic waste each year.

Green, 22, and his team at San Francisco Bay Area e-waste collection center Green Citizen, refurbish 30 cell phones a day to put back into customers' hands.

If you don't chuck your electronics down the trash chute (and please don't,) the most likely cycle is that the phone will be refurbished and resold, one way or another.

Of the appliances that come through Green Citizen'… Read more

How phones are 'optimized,' and why you should care (Smartphones Unlocked)

When you strip it all away -- the e-mail and texting, the voice navigation, and Angry Birds -- your smartphone isn't a smartphone at all. It's a radio.

The job of a radio is to detect, receive, and maintain the signal that leashes the cell phone to the network. When you turn on your phone, it chirps out data that lets the network know another cell phone has hopped on board.

The network authenticates the phone, and the phone is free to send and receive data or calls. In other words, more fundamentally than software and the processor, … Read more

Smartphone battery life: 2 problems, 4 fixes (Smartphones Unlocked)

Imagine a smartphone that charges completely in 5 minutes and lasts a full 10 hours before running on empty. Crazy, right? Toting along the charging cord is just another part of life with 4G streaming and a power-hungry screen.

Back in January, Motorola's Droid Razr Maxx offered the first real glimmer of hope for long-life batteries with the 3,300mAh ticker that dwarfed the battery in any other available handset -- it ran for 19 hours in CNET's tests, a longevity that hasn't been reproduced since.

That leaves the question I get asked over and over again: … Read more

Sony's Xperia Go rugged enough for the great outdoors

Smartphones have become part of daily life but are often too delicate to withstand everyday abuse. Not so for the Sony Xperia Go, an Android handset built to shrug off treatment that would destroy typical mobile devices.

CNET UK took the Xperia Go for a spin, a few dunks, plus crevice-clogging dust-ups to put this rugged machine through its paces. … Read more

Five things you didn't know about data testing (Smartphones Unlocked)

At 10:30 in the morning a few weeks ago I hopped into a plain white van, a mysterious briefcase carefully laid out on the passenger's seat abuzz with phones.

Into the afternoon, the driver answered my probing questions about long hours on the road, awkward run-ins with the cops, and flashed guns. This was no police surveillance ride along; my driver was merely sharing a day in the life of an independent cell phone network tester.
