The Wi-Fi Alliance website recently posted the official Wi-Fi certification for the T-Mobile version of the upcoming Alcatel Idol Pro 4. The Windows 10 Mobile "superphone" still doesn't have an official launch date.

The certification was posted May 25 on the site. Alcatel has confirmed it is working on a high-end smartphone with Windows 10 Mobile in the past for a launch sometime this summer. Rumors about its hardware specs have included things like a 6-inch display, a Qualcomm Snapdragon 820 processor, 4GB of RAM and a 22MP rear camera, but none of them have been confirmed.

T-Mobile currently sells the lower-end Alcatel Fierce XL with Windows 10 Mobile for $139.99. Along with AT&T and its subsidiary Cricket, it is one of the few U.S. carriers to offer a Windows 10 Mobile device.
