Basically, only ~8% of customers who traded an old BlackBerry phone for a new handset claimed loyalty to the brand, while the overwhelming majority of ~66% of customers has went the path of the iPhone. Another %7 are heading towards a new Samsung device. Adding insult to the injury, 42.1% of the website's customers are trading a trusty old BlackBerry for the iPhone 4 - an aging device that Apple has now stopped updating. Only 5.26% are switching to the latest iPhone 5S.
The most traded-in BlackBerry device on the website is the Bold 9790, introduced November 2011. Interestingly, BlackBerry recently restarted production of the Bold 9900, a model that's a good four months older than the 9790.
