Sprint has added some new plans for those of you who use mobile broadband devices for data connectivity. You can now get unlimited 4G data and 3GB of 3G data for $45 per month. If you need 10GB of 3G data, you can grab that for $90. (This, too, comes with unlimited 4G.) These are in addition to plans Sprint previously offered (5GB of 3G + unlimited 4G for $60). And if you already pay for unlimited data on phones (which would be everyone with a smartphone), you can get all of these plans discounted by $10. Pretty decent options, I’d say. (Though given Sprint’s shoddy 4G coverage, I can’t say the 3G would last a heavy user long.) [Sprint via Fierce Wireless]
