I bought this one few months ago from DX: http://www.dealextreme.com/details.dx/sku.32444 It is an original Nokia battery, and atleast the one i've got from them is completely original (no fake). The capacity is also equal to any other bl-5j nokia batt (i have 4 of them), so for those looking just for an original replacement, this is the perfect deal (for the price, of course).
