Hello: I am considering the merits/feasibility of using a FreedomPop WiFi device with my iPhone 4S for internet access. The 4G service is not available in my area, but 3G is. I think 3G may be free, but I am not 100 percent clear on this. I understand that 3G is slower, but if it is actually free I can deal with this. It is my understanding that FreedomPop uses Sprint's 3G network. However, this shouldn't matter if I am connecting to the FreedomPop device via WiFi. Any info you might have will be a lot of help, as I am hesitant to buy a FreedomPop hotspot until I am somewhat assured of my ability to use it with my iPhone.
