Xiaomi, China’s remarkably cheap potential iPhone killer, met with an awful lot of interest when they started taking preorders for the phones, which will begin shipping later this month. In fact, they sold 300,000 handsets – their preorder limit – within just 34 hours. It seems not all of those preorder customers were adoring fans; or perhaps they’re fans that have been tempted by the chance to make some money, but with high demand and a low supply, people have begun selling their Xiaomi preorder numbers on Taobao and other Chinese ecommerce sites.
