Good day to all! Can anyone please help me with my Samsung Galaxy S II SK Telecom - Model SHW-M250S? I want to know all of its features and specifications though I tried searching for it in Google and I can't find any good info about it. I got the phone from my cousin (I can't ask her anything more about the phone she's kinda busy because of her work in the medical field) , though when I received it I think its not the original Android installed? In the OS info, it says Android 4.0.3. I'm also trying to verify if this version of the S2 have NFC.

P.S.: Please do also help me familiarize with Android terminologies like flashing, rooting, etc.
