The Sony Xperia E Dual (C160X) has now appeared on the PTCRB website. There will be two regional variations of the handset (C1604, C1605) that are due to launch in February 2013. Only one version (C1604) seems to be certified right now, with firmware version 11.1.A.0.53. As the Sony Xperia E Dual will launch with Android 4.0.4 Ice Cream Sandwich, we expect this to be ICS firmware.
The Sony Xperia E (C150X) and its Dual-Sim Sibling (C160X) have a 3.5-inch (320 x 480) TFT display powered by a 1GHz single-core MSM7227A Snapdragon S1 chipset, 512MB RAM, 4GB internal storage and microSD memory card slot. Other features include a 3.2MP sensor with VGA video recording and a 1500mAh removable battery.
