Correction on prices and more The product is a WiMAX 4g sleeve for your iPhone4 it cost $99 to buy, you then get 500MB of free data a month! I currently use a clear hotspot called th iSpot. I gets service in most all of the Vegas valley. But Fpop gives me the ability to save 25/mth plus consolidate two battery powered devices I have to carry around. I stream pandora a lot on the road and use the Internet and m clear usage is right around 500mb so this should work well.
