BlackBerry is Kim Kardashian's favorite phone brand [1], and the company thinks it can become yours, too. With its new Trade Up initiative [2], BlackBerry is offering to buy functioning iPhones from Apple devotees for over $500, an effort to promote the new Passport [3] phone — and it just might work. Any iPhone user willing to buy a Passport from BlackBerry's website [4] or Amazon will receive the trade-in value of their phone, plus a "top up" bonus in the United States and Canada.

This offer has been called everything from genius to desperate, but there's no denying that such a lucrative program will test the loyalty of many smartphone users. Would you ditch your iPhone for a big payout?
