Yes, the latest smartphone from Motorola Slinky Delgado just cleared the FCC, but before you get too excited, nothing has changed. By all appearances, the XT615 is focused exclusively on the international market with WCDMA 2100/900 MHz dual band. Of course, it is certainly useful here in the States (a pinch) with Quad-band GSM support, but if you need a slim, ultra-fast LTE, which are much better with its more powerful brother. Oh, damn it.
