Sprint is shutting down its WiMAX data network on November 6th, 2015

Still clinging on to that beloved EVO 4G for dear life? You're going to have to upgrade in the near future. Sprint has confirmed a recent Android Central leak revealing that it will shut down its WiMAX network on November 6th, 2015. If you haven't made the switch to LTE-based devices on your personal account, you'll get an official warning 180 days (i.e. about six months) before the older network goes offline for good. The date isn't completely surprising -- Sprint had previously hinted it would shutter the service next year -- but it now gives you something to mark on your calendar.
