The new banana shaped flex-display based device from LG will be coming to U.S. carriers soon. The official announcement will probably be at CES next week. In the mean-time, press images of the device for T-Mobile and AT&T just leaked online, as you can see above. Of course, both devices look identical save for the carrier branding you can see in the display. Their model numbers are very close as well with D950 and D959.
The other thing to note in each display is a date: AT&T's is March 17, and T-Mobile's is February 12. This might not mean much, but it could be a hint at the final launch dates of the devices. We will keep an eye out during the big tech event for any further details.
