Engadget is reporting that Motorola has filed documentation at the FCC for a phone with a designation of XT1058. The documentation shows LTE bands compatible with AT&T and NFC.
I hope that this is announced next week purely to rub it in to all the blogs that were reporting that it was delayed. In my opinion something cannot be delayed before there has been an announcement of it in any capacity. Reporting that a device or software will be delayed before it has been acknowledged to exist is just crazy talk.
