Now here's a novel idea - a carrier actually helping you save money on your bill. That's exactly what US Cellular is providing with a new app that just landed in the Play Store.
Basically, the app sits idly in the background, watching for "partner" Wi-Fi hotspots. Once it locates one, it automatically connects, which ultimately saves you, the customer, money on your bill (or at least conserves some data). Pretty rad, no?
