Has anyone used freedom pop? It claims to give 500mb of free 4g a month. There have been a few reviews by WSJ, TechCrunch, etc. but they all say pretty much nothing about the service. And I can't get anything out of the website without giving them an email address (a slight red flag). I see on the home page that they offer sleeves for apple products. But in some reviews they discuss hotspots, etc and you only have to pay for a deposit for the device. Free Wireless Internet | Free Internet | 4G Wireless Internet - FreedomPop Just curious. Thanks!
