The rumoured next Google Phone dubbed as the Moto X may be released in the United States soon.

The new Moto X will be heading to AT&T, Sprint and Verizon Wireless as seen in the recent FCC filing for the device.

When the Moto X was first announced several weeks ago, Motorola boldly proclaimed that unlike previous Motorola phones, which found themselves as exclusives on American carriers, the Moto X would arrive on a number of different carriers, giving consumers the same amount of choice afforded to iPhone 5 and Galaxy S4 buyers.

The Moto X has been no stranger to the FCC. In fact, several different variants have emerged in recent weeks with the XT1058 thought to be the AT&T Moto X, the XT1056 thought to be the Sprint Moto X and the XT1060 thought to be the Verizon Moto X. Now, it appears that those models will be joined by a Moto X for regional LTE carrier U.S. Cellular.

An FCC filing, discovered by Blog of Mobile, points to a device called the XT1055 that is believed to be the U.S. Cellular Moto X. If true, and it likely is, it means that the Moto X is coming to at least four carriers in the United States with the only major carrier left out, at least for the moment, being T-Mobile. It's not clear if T-Mobile will join the party but given its LTE capabilities and its unique off-contract, data plan structure, it would be strange to see Motorola leave the Moto X off the Magenta carrier.

Rumour has it that the Moto X set to be released in October will run with Android5.0 Key Lime Pie. It will sport 4.7 or 4.8 inches of 1080 screen display. The device will be powered by a quad-core processor.

The rear camera of the Moto X is a 12MP Exmor camera from Sony. It is speculated that the smartphone will have a huge storage up to 128GB with microSD card slot. Lastly, it will pack a 3300 mAh battery.

The Moto X phone will have some incredible internal specs, according to early leaks. It is reported that the Moto X phone could have a "5-inch display...In addition, the camera is reportedly 10 megapixels, less than the 13 megapixels on the Samsung Galaxy S4 but more than the 8 megapixels on the iPhone 5." The specs will rival the iPhone 5 and Samsung Galaxy S4, since Motorola Mobility is betting so heavily on the phone. Reports also claimed that Moto X phone could be cheap just like LG Nexus 4.

However, neither Google nor Motorola confirmed that it Moto X is indeed the next Google phone.
