In exchange, iPhone 4S, 5c, 5s and 6 owners can get up to $550, with proof of purchase of a BlackBerry Passport -- if qualified, payments will then be made via Visa Prepaid Card. The offer, which is only available in the US and Canada, runs December 1st to February 13th of next year, and it's a solid option for those interested in that trademark physical keyboard and the square-shaped display. Best Buy, for instance, pays about $460 for an iPhone 6 with 128GB of storage.
