This is shaping up to be the year of the awesome cell phone (that isn't produced by Apple). The awesomeness began with the release of the Nokia Lumia 900 early in the year. After that, around CTIA 2012 in New Orleans, HTC dropped their Evo 4G LTE, a Sprint phone that dazzled us with its incredible camera, relatively fast speed, nifty kickstand and amazing screen.

Not to mention the various HTC One flavors of mobile phones. Not to be outdone, Samsung released the European version of the Samsung Galaxy SIII around the same time...and well...our buddies across the pond came to the conclusion that it may be the best mobile phone ever.

Microsoft even jumped into the fray by announcing that Windows Phone 8 handsets will be available this fall.

Team America for the win!

Of course, the mobile phone marketplace being what it is -- confusing as all get out -- the Samsung Galaxy SIII that our European brothers and sisters got their warm-beer-loving hands on turned out to be decidedly different than the device that eventually made it to the States.

While many of the specs remain the same: 8-megapixel camera, 4.8-inch Super AMOLED HD screen, excellent battery life, and brushed poly-carbonate housing (that comes in "Marble White" and "Pebble Blue"), the handset that AT&T, T-Mobile, Sprint, Verizon and US Cellular will be releasing in the States boasts a few rather significant differences. Some might even call them upgrades.

Much has been written about the fact that the device that ultimately showed up in the States rocks a dual-core Qualcomm Snapdragon S4 processor and twice as much RAM as the European model: coming in at 2GB. That said, the question remains, "How does this model compare to its brother across the Pond?" In a nutshell, not that much.

While the Snapdragon S4 processor that's in the American version isn't as robust as the quad-core processor in the European model, the Samsung Galaxy SIII, for all intents and purposes, is a fast phone regardless of which one you play with. And aside from running Speedtest, most users will be pressed to notice the difference.

Additionally, the American cell phone marketplace differs from that of Europe in that it's extremely carrier specific. Such that the Samsung Galaxy SIII experience will differ slightly from carrier to carrier.

How does AT&T do?

We got our hands on the Samsung Galaxy SIII (AT&T) mobile phone and put it through its paces. Depending on where you are, your experience may differ from ours. We tested the Samsung Galaxy SIII (AT&T) mobile phone in San Francisco, Oakland and Kona (on Hawaii's big island) and had strong signals in all three locations.

Each U.S. carrier likes to pack their phones with their own software. To that end, AT&T is slightly better than the rest of the pack.

Ice Cream Sandwich.

Setting up this relationship was super-simple, and once we did it, the devices would automatically talk to each other. As long as the portable Wi-Fi hotspot feature was enabled on the phone.

While the Nokia Lumia 900 is super-sexy, at around six months old, it's already starting to look a little long in the tooth, and well, who really wants to plunk down $100 for a phone who's obsolescence was just announced by Microsoft at their recent Windows Phone Summit in San Francisco?
