Hi Sorry for noob question. I've been trying to search for the earlier posts but couldn't get any light.

I went to digital mall just now and there's this Samsung authorised dealer selling Galaxy S2 white at RM1950. I went to other shop they only selling RM1750 for S2 white and they said warranty under samsung. Both G version. Which one should I buy from? How to differentiate between original and water set?

p/s: i used an iphone 4 but i lost it but my contract still going. wanted to try Samsung.

That's why until now i have not bought the phone. Why is it a huge difference there? how to differentiate which one is original?
