(Image source: crackberry.com) BlackBerry Ltd (NASDAQ:BBRY) will sever ties with T-Mobile US Inc (NYSE:TMUS) after their current licensing agreement expires on April 25th. According to BlackBerry, their strategies are no longer in line with T-Mobile. BlackBerry was upset that during its trying times, T-Mobile was promoting free iPhone to BlackBerry customers to leer them away from the failing smartphone maker. I guess this is payback from BlackBerry.
