Gigabyte has announced not one, not two, but four dual-SIM Android phones at the Computex computer expo in Taipei, Taiwan. All of them run on Ice Cream Sandwich Android 4.0 out-of-the-box and provide dual-SIM standby capability. The Gigabyte GSmart M1420 is the one with the best overall specifications of the four — a 1GHz MediaTek MT6575 processor, 4.3-inch WVGA display, 8 MP camera with autofocus and LED flash, and a 1.3 MP camera on the front.

The GSmart M1320 has a 1GHz processor, 512 MB RAM, a 4.0-inch WVGA (480×800) display, 4GB internal storage, and a 3 megapixel camera at the back.

Next up is the G1362, which features a 1.2 GHz Qualcomm processor, 512 MB RAM, 4GB internal storage, 4.3-inch WVGA screen, 5 megapixel camera with autofocus and LED flash (along with a VGA camera on the front), and GSM/EDGE/WCDMA/HSUPA connectivity.

The smallest and weakest of them all, the G1342 has a 3.5-inch 320×480 (HVGA) display, 800 MHz Qualcomm MSM7225A processor, 512 MB RAM, 1GB storage, and a 5 megapixel camera on the back and a VGA front camera.

The release or launch dates aren’t known for any of the four dual-SIM devices at this point, but we’ll let you know when more info gets released.
