T-Mobile CEO John Legere shared a link to the T-Mobile website offering a look at Samsung's upcoming Galaxy S6.
Legere tweeted the link to a page where a single image reveals a slender, metal, curved smartphone emitting a pink light.
Earlier this month, leaked images seemed to confirm rumors that Samsung was to launch a new flagship device with a curved, edge-to-edge display, and to indicate that aluminum would replace the plastic body of previous models.
Other information suggests the handset will be faster and more powerful than an Apple iPad Air 2 and have a 5.1-inch display, a 5-megapixel front-facing camera and a huge 20-megapixel rear-facing camera.
Samsung is to reveal the Galaxy S6 on March 1.
