I was browsing youtube videos about the Nokia N900, and I’ve found video showing fake Nokia N900 phones available to buy in China. In video you can see that fake N900 model is very well copied and there are almost no difference from original when we are talking about visual apperiance. But wait for phone to turn on and you will see fake Symbian S60 in fake N900 hardware (Symbian on N900, :D) Of course there are two sim slots and box is iphone style, so if you are buying N900 watch for Maemo menu pics of phone you are buying. :D
This is good solution only if you don’t have enough money for original, and you want to have best phone among your friends, although only you know what it is under housing.
