BlackBerry users on T-Mobile who want to upgrade will now receive $250 towards any BlackBerry phone, or $200 toward any other manufacturer’s phone in T-Mobile stores. The deal was introduced after a recent furor between BlackBerry and T-Mobile in which the carrier sent out an email to its BlackBerry-using customers that urged them to upgrade to an iPhone 5S for a discounted price. In response, BlackBerry CEO John Chen penned an “outraged” blog post in which he blasted the “clearly inappropriate and ill-conceived marketing promotion,” and lauded the significant number of BlackBerry fans who’d contacted T-Mobile CEO John Legere directly to complain about the email. T-Mobile responded quickly to Chen’s post. It first offered expedited shipping of the BlackBerry devices on its online store, but the offer — currently only applicable to a refurbished version of the manufacturer’s Q10 phone and an older BlackBerry 7 model — felt limited.
