Nokia 5130 XpressMusic: ~65 million
Nokia's 5130 handset was the first music-oriented feature phone out of the Finnish phone maker, and went on to sell in the region of 65 million, based on earlier figures from Nokia. It was particularly popular in emerging markets, thanks to the inclusion of the Opera Mini browser, allowing users to conserve data on the go. But equally, it was popular among Westerners who found the device to be a cheaper 'iPhone' like device — with a mix of high-quality audio and cellular features — albeit without the range of apps, and despite the fact that the iPhone hadn't even been invented by this point.
