As of February 21st, T-Mobile will give you $200 for your existing BlackBerry, and $250 if you're upgrading from a T-Mobile BlackBerry to a BB10 device like the Q10 or Z10.
T-Mobile's move follows a recent blog post by
BlackBerry chief John Chen, who criticized T-Mobile's
marketing to BlackBerry users when the carrier enticed them to
switch phones in a recent promotion.
"We?ve been working overtime here to find the best possible
way to show BlackBerry users exactly how much we appreciate
and respect your passion for and loyalty to T-Mobile and to
BlackBerry," said Mike Sievert, T-Mobile Chief Marketing
T-Mobile says that the offer is the same regardless of the
device's age, so long as it's in good condition.
