I was just at BestBuy and noticed that Virgin Mobile now has a MiFi device. The thing that caught my attention is that were advertising an Unlimited Plan for only $40 a month, and you don't have to sign a 2 year contract. They use the Sprint 3G network for service. Has anyone tried this. You don't hear much about Sprint 3G network and how fast or reliable it is. Anyone have a Sprint phone? I didn't buy the WiFi Ipad because AT&T is almost non-existent where I live.
