Possibly old news, but a quick share for you all -
If you're one of the folks like me who upgraded to an LTE phone early, but live in an area where WiMAX was available and reliable, this might be interesting to you:

$35/month for 2GB 3G data and 10GB WiMAX data, the latter of which is interesting. This is a very interesting alternative to the new hotspot plans Sprint offers... $20 for 2GB, $50 for 6GB ... because there's no LTE yet in many of the big cities, whereas WiMAX is still available.
Here in the DC area specifically, WiMAX does and has always worked very well. I thought I would share this with you lot as I'm very tempted to drop the hotspot feature on my Sprint plan and pick up one of these instead...more data for less money, and as strange as it is to say this, having WiMAX again would be nice, at least until LTE goes live.
