Sprint taking the "unlimited" out of unlimited 4G mobile broadband plans

Sprint is the last remaining of the four main carriers to offer truly unlimited 4G data with no caps or speed throttling. Their mobile hotspots such as the Overdrive have been available on a monthly plan that included unlimited 4G data courtesy of Sprint’s WiMax network while a 5GB cap would be in place when in 3G areas.
In addition to tablets and mobile hotspots, affected devices include netbooks and laptops with built-in WiMax support and USB connection cards. Sprint is making this change effective in November but dates will vary depending on the billing cycle. Once that change happens there will be three different plans to choose from; a 3GB, 5GB and a 10GB option. Instead of speed throttling Sprint is going the way of charging overages as every extra MB of data will cost $.05.
