Hello guys, I've recently decided to buy a new Samsung Galaxy S3 phone, but after searching I see different versions, and very different prices. Could you please help me learn which is the DEFAULT and ORIGINAL version made by SAMSUNG, and what would the price be? I searched in google shopping, but I see prices from $250 to $800 which is wierd lol. I don't need to much space for it, 8GB or 16gb is more than enough. Any help, would be appriciated! Thankx!
