It appears to be an end of an era. Thehas culminated in a break between the two companies.
In a rare move, BlackBerry announced Tuesday that it is not renewing its deal with T-Mobile to sell BlackBerry devices. The current agreement is set to expire on April 25.
"BlackBerry has had a positive relationship with T-Mobile for many years," BlackBerry CEO John Chen said in a statement. "Regretfully, at this time, our strategies are not complementary and we must act in the best interest of our BlackBerry customers. We hope to work with T-Mobile again in the future when our business strategies are aligned."
The tiff between the companies fired up a couple of months ago when T-Mobile started an e-mail campaign prompting customers to dump their BlackBerry devices in favor of an iPhone. That, in turn, rallied faithful BlackBerry users into tweeting the hash tag #CHOOSEBLACKBERRY10 to T-Mobile CEO John Legere.
Chen, meanwhile,, noting that he was outraged by the campaign, and felt it was "inappropriate and ill-conceived."
"I can assure you that we are outraged too," he wrote. "What puzzles me more is that T-Mobile did not speak with us before or after they launched this clearly inappropriate and ill-conceived marketing promotion."
While T-Mobile has backpedaled ----- it appears BlackBerry had enough.
BlackBerry said Tuesday that the feud wouldn't affect customers using its devices on T-Mobile.
"We are deeply grateful to our loyal BlackBerry customers and will do everything in our power to provide continued support with your existing carrier or ensure a smooth transition to our other carrier partners," Chen said.
T-Mobile Chief Marketing Officer Mike Sievert said in a tweet that existing customers would be able to keep their current corporate discounts. An official announcement is slated for tomorrow morning, he added.
