BlackBerry criticized T-Mobile in February for pushing iPhones to BlackBerry customers.

The two companies have been trading harsh words for a week, and now T-Mobile is offering a $200 credit to trade in their Blackberrys.

BlackBerry rededicates itself to physical keyboards as the company tries to get out of a death spiral.
