T-Mobile accidentally leaked the newest Windows 10 phone, the Alcatel Idol 4S, ahead of the handset's official announcement during Microsoft's Surface event in New York City today. The handset-and-VR-headset bundle was originally released in July as a low-cost competitor to Samsung's Gear VR, though back then, the Idol was still running Android. T-Mobile is now offering the Idol 4S bundled with a VR headset as well as a 45-day trial subscription of Hulu, a 60-day trial subscription to Groove Music and a free copy of Halo Spartan. There's no word yet on pricing or availability.
