So i figured out that Target in my local area uses Sprint for public wifi, and even possibly for its devices connection to Minneapolis. How common is this to see? Its obviously it is wimax due to higher pings 75-100 usually, and speeds 2-6mbps. And what will happen once wimax shuts off?
If you shop at Target and need a new phone, download cartwheel, and get 20% off on any sprint phone, plus get a minimum $100 gift card towards the phone if you do a trade in. Pretty good deal!
