I SAY IT AGAIN, THIS IS NOT A NEW VERSION OF NITDROID, JUST AN INTERFACE MOD. This DOES NOT ENABLE voice call, camera zoom/focus or any non-implemented functions on e-yes's original NITDroid N12. Battery drain is also the same.
Heck, I'm Chinese and you know how hard it is for us to access Facebook, Twitter, Youtube, etc. for the censorship here. Nontheless, I'll try and give a short video tour, though I can't promise.
