It was only a few days back that Samsung announced the dual-mode LTE variant of the Galaxy S4 mini (and its bigger brother), and now the device has been found visiting the FCC to get its radios certified. The model number is listed as GT-I9197 and it is supposedly headed for Australian carrier Optus.
Thanks to the dual-mode LTE, the S4 mini will be able to switch between TD-LTE and FD-LTE networks, to provide LTE coverage to users no matter which part of the world they might visit (not counting jungles, islands and the like). Samsung is yet to officially announce where the dual-mode LTE S4 mini will be launching, though we can expect to see it in every country that has LTE networks in operation.
As for the specs, the Galaxy S4 mini comes with a dual-core 1.7GHz Snapdragon 400 processor with Adreno 305 GPU, 1.5GB of RAM, a 4.3″ qHD (540 x 960 pixels) display, 8-megapixel rear camera, 1.9-megapixel front-facing camera, 8GB storage expandable via microSD cards, Wi-Fi, HSPA+, and NFC connectivity, a 1,900mAh battery, and Android 4.2.2 Jelly Bean with TouchWiz Nature UX 2.0.
