The filing reveals the back of the phone, which aligns with previous leaks from earlier this year.
Other information pulled from the filing includes: AT&T's LTE bands (including support for legacy networks 2G, 3G, and HSPA+). Sorry Verizon subscribers, there isn't any indication that the smartphone will support the CDMA network that its smartphones operate on.
Previous leaks indicate that the phone will have a 4-inch HD screen, Qualcomm Snapdragon S4 Pro processor, a non-removable 2200mAH battery, and 2GB of memory.
This smartphone would potentially be Google's next flagship smartphone. Google has yet to work with Motorola Mobility , a company it acquired a year ago.
Google is gearing up for its biggest event of the year this week, the Google I/O developer conference in San Francisco.
The Verge points out that it's highly unlikely that the phone will make a debut at I/O later this week, but we can still hope.
