Smartphone manufacturers are bringing out the big guns as we move into the final months of the year. While much of the attention will undoubtedly center on Apple's new iPhone 4S, Android fans are spoilt for choice this holiday season. Anticipation is growing with Android 4.0 (code-named Ice Cream Sandwich) expected to arrive any time now.

We also have high hopes for Microsoft's renewed mobile platform, but we are still waiting for the latest Mango-powered hardware to hit U.S. shores. In particular, Nokia's first Windows Phone devices. Notably absent from this update to the Smartphone Buying Guide are webOS devices, which were put on life support last August. RIM's BlackBerry devices have also failed to impress lately, so you will note the company is represented by a single model, the BlackBerry Bold 9930.

Without further ado, check out our selection of the hottest devices currently out there. Each phone is listed alongside its feature highlights, specs and prices, broken down in three categories depending on its time of release. We've added metascores from our Product Finder engine besides each phone to further aid you in making well-informed decisions on your next purchase.

Motorola has revived its popular Razr brand with the new Droid Razr. The device features a stainless steel frame with Kevlar on the back and includes a dual core 1.2GHz processor, 1GB of RAM, a 4.3-inch display covered with Corning Gorilla Glass and an 8MP camera. This ridiculously thin 7.1mm phone can run on Verizon's LTE network and access what Motorola calls Moto Cast, a "personal cloud" that let's you share files in the cloud. It also offers a wealth of optional accessories including screen and keyboard docks and portable chargers.

88 86 Reviews The iPhone 4S features an upgraded A5 dual-core processor, a faster wireless network and an 8MP rear camera with improved optics. The 4S retains the same size and shape of the iPhone 4, categorizing it as an evolutionary upgrade rather than a revolutionary device. Its standout feature is a new voice assistant program called Siri that's described as an "intelligent assistant that helps you get things done just by asking."

The second generation of Windows Phones with upgraded specs and Mango preloaded is set to arrive this holiday season. We'll have to wait a bit more until they officially hit U.S. shores but there are some interesting prospects on the horizon: HTC will be releasing the high-end Titan, wielding a 4.7-inch SLCD display, dual cameras and a single-core 1.5GHz processor, as well as the Radar featuring a more modest 3.8-inch screen and a 1GHz processor.

Meanwhile, Samsung is adding the Focus S and Focus Flash to its lineup. The first is an update to the original Focus with a thin 8.55mm body, a 1.4GHz processor under the hood, and a 4.3-inch Super AMOLED Plus display. The Focus Flash is a lower-end offering but still carries a a 1.4GHz CPU. It has a 3.7-inch Super AMOLED screen and a 5MP shooter on the back.

Little details have been mentioned about Nokia's first Windows Phone handset but we might hear some news at the Nokia World trade show, which takes place October 26-27 in London. Rumored specs include an 8-megapixel camera with Carl Zeiss optics and a 3.7-inch Gorilla Glass-protected touchscreen.

Motorola's first iteration of the Atrix smartphone promised a lot. It had a 4-inch "qHD" (960x540) display, thin body, and ability to gain PC-like functionality with either a laptop-sized expansion dock or HD multimedia dock. Although it wasn't the bit hit that the company was hoping for, its follow-up picks up the pace with an improved camera, more storage, and 'true' 4G speeds (AT&T’s HSPA+ network topping out at 21Mbps). You'll also get a 1GHz dual-core processor and the same expandability that its predecessor offered -- all for a lower price tag starting at $100.

81 12 Reviews The Motorola Droid Bionic has had a storied past. Although it was originally announced way back at CES in January, Motorola went back to the drawing board and came up with a device that could be a doppelganger for the Droid X2. But don't be fooled by appearances; this dual-core phone runs on Verizon's speedy LTE network, supports a range of accessories that utilize its Webtop software, and offers solid battery life. It sports a 4.3-inch, qHD (540x960 pixel) display and can record 1080p HD video.
