[Q] Xperia E3 version topic

Hi,
My contract with the phone carrier is ending in June and i planed to get this phone, because it's the cheapest one i can get that has a stable/semi-stable CM12 rom.
I am a member of the Glade Dev team and i plan to port it for E3. But i can't be sure if the device i am getting will be D2203. So can someone tell me what specs does the D2203 have and what are the differences compared to the other versions ?

The phone from my carrier has :
4.5" 854 x 480 screen.
5MP back and VGA front camera.
1.2 GHz Quad-core Qualcomm MSM8926-2 CPU
1GB of RAM

Thanks in advance!
