On the original article it says that the sales jumped after Ohijärvi. I'm a bit dubious about that as well. I can't imagine Ohijärvi having too big of a influence on direct sales. At best this could mean that the statement is linked to those partnerships, that would be some major operators or retailers and Jolla finally selling the phone in China. Actually outside of that I can't understand how the demand could increase so much in the coming months.
