BlackBerry’s CEO, John Chen, blasted T-Mobile last month after the carrier launched an apparently innocuous promotion that would reward customers for switching from a BlackBerry phone to the iPhone. In response to the outrage, and in a move that appeared designed to appease Chen and his company, T-Mobile introduced a deal that would offer money off a phone upgrade to T-Mobile customers with BlackBerry phones. Those switching from BlackBerry to another manufacturer’s device would receive $200, while those moving from an older BlackBerry to a newer model would receive $250. Chen’s outrage appears to have backfired on BlackBerry.
