Jimmy thanks for all you have done for me but it seems as I guessed it's a fake, a cheap one but we live in a country that everything is rare and expensive.For example this R4 price here is 20 $ and the white one that i borrowed from my friend (which is very rare to find here) cost him 40 $! But as I see here the best R4 is only about 10 $! unfortunately there is no direct shipping from around the world to Iran so we have to buy these trashes from go-between seller.There is no way at least I can buy the white one from my friend because he doesn't need it anymore
Thanks every one for helping
