BlackBerry's (NYSE:BB) new Q10 smartphone will be available for preorder for business customers on T-Mobile's website April 29, according to an online statement by the carrier.

The Q10 will sport 4G LTE connectivity, with a physical keyboard and touchscreen display. The new smartphone will add to a growing list of T-Mobile 4G LTE phones, including the recent iPhone, which launched on the carrier earlier this month.

Drew Kelton, executive vice president of business markets at T-Mobile, said, "With the powerful combination of BlackBerry's new BlackBerry 10 platform, the company's long-standing security features, and BlackBerry's best QWERTY keyboard, the BlackBerry Q10 will be another great smartphone option for our business customers." 

T-Mobile recently ran into problems selling the much-anticipated Samsung Galaxy S4, pushing the online ordering date back from April 24 to April 29. T-Mobile and BlackBerry haven't said when the Q10 will be available, or what the price will be.
