For those who can't wait for the Samsung Galaxy S3's U.S launch this summer, an unlocked GSM version of the phone is available for pre-order on sites such as Amazon and Expansys.

Amazon is shipping the device through Tailwind International priced at $799.99. The phone will be released on May 29 and most customers should receive it between June 1 and June 4, according to the site.

On Expansys the phone is available for $694.99, but the site has not specified am estimated shipping time.

The S3 heralds a 4.8-inch screen, 1.4 Ghz quad-core 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 has launched a Face Recognition feature on its latest phone in an aim to the make the Smartphone experience more natural. The phone uses its front camera to identify the user's eye movement and insures 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, Siri-Like voice recognition system dubbed S Voice.

The service allows 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.

The Samsung S3 will first become available in Europe at the end of May, followed by launches in Asia, the Middle East and Africa. The 4G version of the phone will go on sale in the U.S and South Korea during the summer.
