The highly anticipated Samsung Galaxy S3 will finally arrive in stores on all four major U.S. carriers June 21.

Those who preordered the phone will get staggered shipments between June and July, depending on the carrier; however, with AT&T, Verizon, Sprint and T-Mobile all launching the phone at roughly the same time and price -- which network will the Galaxy S3 perform best on?

All U.S. models of the phone run on the Android 4.0 Ice Cream Sandwich and Samsung Touchwiz. This particular model heralds the Snap dragon dual-core S4 processor, clocked at 1.5 GHZ. It weighs 133 grams and comes with a 2100Ah battery.

The most significant difference between the carriers is connectivity. The T-Mobile variant doesn't support LTE, and the other carrier's models do not support T-Mobile's HSPA+. 4G LTE will also vary in speed depending on the network and coverage of the carrier.

While Verizon generally takes the lead for LTE speed and coverage, AT&T will stand out for the exclusive launch of the red Samsung Galaxy S3, expected this summer.

The Galaxy S3 is available in pebble blue and white on other carriers across the world, but the red case will be an exclusive to AT&T.

Unfortunately, pictures of the red phone have not been leaked yet.

The addition of the Samsung Galaxy S3 to our portfolio of 4G-LTE devices gives our customers another truly cutting-edge smartphone to choose from, said Jeff Bradley, senior vice president, devices, AT&T Mobility.

The phone's bloatware also varies. Each network will tout its own version of Samsung's new apps, such as S Voice, a Siri-like intelligent personal assistant and navigator, and AllShare Play, which allows users to play content saved on various devices.

The S3 heralds a 4.8-inch screen, Qualcomm S4 processor, voice control and face recognition. The new Super AMOLED display is 22 percent larger than its predecessor, bringing the phone into the Galaxy Note's phone/tablet hybrid category.

Samsung launched a face recognition feature on its latest phone in an effort to the make the smartphone experience more natural. The phone uses its front camera to identify the user's eye movement and ensures it never goes dark or switches off, while the user is looking at the phone.

Samsung has also improved its voice control feature with a sophisticated voice recognition system similar to Apple's Siri, dubbed S Voice. In addition to allowing users to make verbal demands to control their phone, texts and emails can be dictated and photographs can be taken through voice commands using the feature.

The S3 also includes an NFC chip, which enables content sharing -- including video -- through tapping two phones together. The chip can also be used to make mobile payments.

The new Pop up Play feature on the phone enables multitasking, allowing users to open a video in a window on screen, and then use other apps with the rest of the screen.
