Verizon Wireless

Verizon, or Big Red as it’s more amicably known, plays host to a wide variety of excellent smartphones. The best device it currently has to offer (or soon to offer, really) is the Samsung Galaxy S III. With a 4.8-inch 720p Super AMOLED display and 1.5GHz dual-core S4 processor as well as 4G LTE connectivity, this phone is sure to be one of the hottest sellers this summer.

Of course, the Galaxy S III isn’t the only good choice. The Motorola Droid RAZR is a high-quality, super slim phone with many of the same features. Its processor is slightly older and only runs at 1.2GHz; however, its price tag is an agreeable $99 with contract, though you might want to consider the Droid RAZR MAXX which features a much larger battery. A Droid RAZR HD is also due sometime in the near future with beefier specs and an HD display.

Another notable contender is the Samsung Galaxy Nexus, a phone built entirely on input direct from Google and running the purest, latest version of Android. And of course, you can’t forget the iPhone 4S, the latest of Apples iOS phones (though we suggest holding out for the iPhone 5 due later this year).

AT&T

AT&T also has the Galaxy S III; however, it also has a very worthy alternative if you don’t want to wait for the newest Galaxy device to officially launch. The HTC One X is currently alaTest’s top rated phone, featuring a 4.7-inch 720p Super LCD2 display and the same 1.5GHz dual-core S4 processor found in the Galaxy S III. It also has a great 8MP camera and LTE 4G capabilities, and best of all, it’s actually available now.

AT&T also features the iPhone 4S for the iOS aficionados out there, but again, we suggest waiting for the iPhone 5.For WP7 fans, AT&T has the best WP7 device released to date – the Nokia Lumia 900. With its 4.3-inch AMOLED display, 4G LTE, and 1.2GHz processor, it’s the fastest most feature packed WP7 phone on the market, and it’s not even the most expensive.

Sprint

Sprint, of course, will be getting the Galaxy S III as well, but, like AT&T, it has a variant of the HTC One X known as the HTC EVO 4G LTE. It’s really no different from the AT&T model with the exception of a slightly different look and the fact that it’s intended for Sprint’s network.

Sprint’s other great choices include the iPhone 4S and the Samsung Galaxy Nexus. Unlike the Verizon Galaxy Nexus, Sprint’s is a little bit more true to the Nexus name with better Google Voice and Google Wallet integration.

T-Mobile

The Galaxy S III will be coming to T-Mobile as well, but the magenta colored carrier doesn’t have as many compelling alternatives as some of its competitors. The HTC One S is its only device we can really recommend, but it really is a great phone (currently ranked 3^rd on our top phones list). On the inside, it’s exactly the same as its big brother, the One X, and it even features the same 1.5GHz dual-core processor found in the Galaxy S III. The only difference is its smaller 4.3-inch display featuring a slightly lower resolution.

Motorola Droid RAZR

Back in the pre-smartphone days, the RAZR was one of the hottest phones, thanks largely to its half-inch thickness (14mm). Now the RAZR is back, and in smartphone form, sporting Android no less. At 7.1mm thin, the Droid RAZR is currently the slimmest phone on the market, and maintaining its slim figure while sporting a 1.2GHz dual-core processor and LTE 4G capability is even more impressive. On the downside, battery life suffers considerably; however, the Droid RAZR MAXX has a much larger battery though weighs in at 8.99mm thick.

HTC One S

At 7.8mm thin, the One S is one of the thinnest, fastest, globally available GSM smartphones on the market. Its 1.5GHz dual-core Snapdragon S4 processor consistently posts top scores on both performance and battery benchmarks. Unlike most super thin phones, the One S actually stands a solid chance of making it through the day on a single charge.

Samsung Galaxy S III

The Galaxy S III is one of the latest smartphones to hit the market, and as expected, it’s quite thin. At 8.6mm, it’s only 1mm thicker than its predecessor, the Galaxy S II, but the extra girth certainly isn’t wasted space. Sporting a 1.4GHz quad-core Exynos processor, the S III stands to be one of the fastest phones on the market. Its 2100mAh battery also bodes well for its battery life.

Samsung Galaxy Nexus

The Galaxy Nexus, Google’s latest “Pure Google” Android phone, is exceptionally striking with sleek lines and a unique concave display. At just 8.9mm thick, it’s also exceptionally thin. It features similar specs to the Droid RAZR (ie: 1.2GHz dual-core processor); however, it has a larger, higher resolution display. The LTE version of the Galaxy Nexus is slightly thicker in order to accommodate a larger battery.

HTC One X

Recently displaced by the Galaxy S III as the worlds more recent smartphone, the One X is still an amazingly powerful device in a very thin shell. Its 8.9mm thickness won’t be any more noticeably thicker than the S III’s 8.6mm, but the One X has the major advantage of already being available in the U.S. Both Sprint and AT&T carry it (as the EVO LTE and One X respectively). Like the S III, the One X features a powerful quad-core processor; however, some U.S. variants feature a similarly powerful dual-core instead (this may turn out to be the case for the Galaxy S III as well).

Now, there are other super thin phones on the market, such as the Sony Xperia GX, Huawei Ascend P1, and Panasonic Eluga DL1 to name a few. We’ve selected only the most popular of them. Plus, with manufacturers like Oppo and ZTE teasing phones down to 6.2mm thin, we might have to revisit this topic in the not so distant future.

The iPhone

It comes as little surprise that the iPhone made up a good portion of that 6.8 million units, and while Android phones as a whole outsold the iPhone, it’s still an impressive feat considering that the iPhone 4S held the most sales out of any single device (at somewhere around 3 million units). The 4S was also the most returned device following Christmas, and by a rather large margin. The reason for the high return rate is uncertain. It could be that people felt that the 4S didn’t offer much noticeable improvement over their current model, or perhaps they were enticed by the better spec’d Android phones on the market, and tempting after-Christmas sales (which are still going on).

Android Phones

As a whole, Android phones made up for about 55% of smartphone activations on Christmas day, though no single Android device could compare with the iPhone 4S’ impressive figures. But there are definitely still a few notable contenders.

The Galaxy S II

Available on AT&T, Sprint, and T-Mobile, the Galaxy S II gave people a lot of options in terms of plan pricing and coverage – its record breaking specs certainly didn’t hurt either. With its 1.2Ghz to 1.5GHz processor and 4.3 to 4.5-inch screen (depending on carrier), it appealed to many considering an iPhone but wanted a bit more power or screen space. Estimates put Galaxy S II activations around 1.5 million. The only people who couldn’t get in on the action were Verizon Wireless subscribers.

The Galaxy Nexus

Fortunately for those on Verizon, there was a (arguably) better option: the Galaxy Nexus. While it shares a similar 1.2GHz processor to the Galaxy S II, the Galaxy Nexus features a stunning 4.7-inch 720p HD display, a first for smartphones. It also features Google’s latest version of Android and comes 100% free of any manufacturer or carrier bloat. Sales figures on the Galaxy Nexus weren’t overly impressive, though, since it wasn’t marketed all that aggressively, much like the previous Nexus devices.

The Droid RAZR

Instead of going for the Galaxy Nexus, Verizon subscribers flocked to the Droid RAZR, an ultra thin, uber sleek phone with equally impressive specs. Plus you get that bit of nostalgia if you ever owned one of the original Motorola RAZR phones in the past. They really did do a surprising job of capturing the original look in smartphone form.

The BlackBerry Torch

If you’re a BlackBerry fan, you probably already know that the Torch 9810, 9850, and 9860 is where RIM stepped up its game to compete with today’s current smartphones. Now you can have things like 4G, Wireless-N, and even a modern 1.2GHz processor all with the BlackBerry OS 7 users have grown to love.

Did we mention that Smartphone deals didn’t end with the holidays? In fact, many of the huge sales started just after Christmas, and many are still going on. T-Mobile in particular is hosting one last big sale day this weekend. If you’re a T-Mobile subscriber and you’re due for a new phone, you may want to consider the Galaxy S II or HTC Amaze, both phenomenal smartphones.
