Acer’s on the prowl with the release of four new smartphones, including the dual-SIM DX900 that’s been floating around for a while now. All four phones run the Samsung S3C 6400/6410 mobile processor clocking in at 533 MHz, and comes with 3G, WiFi, Bluetooth, micro SD expansion, GPS, Windows Mobile 6.1 Professional, and a 3-megapixel autofocus camera (except the M900, which sports a 5-megapixel camera with flashlight).
