[Video Link] The FreedomSleeve is an iPhone sleeve that connects a 3G iPhone to a "free" 4G network. It can be used as a wifi hotspot, and has a built-in battery to extend the iPhone's internal battery an additional 6 hours. It cost $99 and you get "up to 1GB of free data every month." According to GigaOM, each additional megabyte will cost a penny. Service is expected to start this summer. I hope the service is international.

Public Knowledge's Michael Weinberg, who wrote an outstanding paper on the law and 3D printing, has a new paper, this one on 4G networks with data-caps, and how weird it is to advertise that your network is a) very fast and suitable for video; and b) that you'd better not use it for data-intensive applications. He sez, "Wireless carriers have started to push their new 4G networks. The carriers say that these new networks are amazing, and will allow you to do more, faster, than ever before. What they do not tell you is that you will not be able to use the new 4G networks for very much. That is because the wireless carriers (with the exception of Sprint, which offers truly unlimited 4G connections) have imposed arbitrary limits on their 4G networks. For the average user, this limit is set at 2 GB per month. As a result, just about everything that you would use the 4G network for will put you over your limit. At full speed, you will hit a month's worth of caps in under an hour. In that time, you might be able to download half an HD movie to watch for the rest of the month."

This unfortunate fact is the result of a combination between fast 4G networks that deliver a lot of data and low limits on how much data you can use. The 4G speed means that you hit your cap even faster than you would on the existing 3G network.
