It's never easy to share news of job losses, but that's the state of things at T-Mobile's US headquarters in Bellevue, Wash. Today, the carrier confirmed to us that layoffs are currently underway, which comes in advance of the UnCarrier's merger with MetroPCS. While T-Mobile representatives withheld specifics, The Seattle Times reports that somewhere between 200 and 300 employees have been laid off, whose jobs range from administrative assistants to senior vice presidents. This news follows reports of job cuts earlier this month, which are said to have affected more than 100 people in the marketing department and other divisions. For its part, T-Mobile suggests the decision was made in order to better focus its resources, which seems plausible, given its scrappy new approach in the mobile industry. It's certainly a bitter pill to swallow, but you'll find the carrier's statement after the break.
