Do you feel punish because AT&T, or Verizon data speed suck in your area? Or you don’t have a carrier that is not compatible with the iPhone 3G bands, like T-Mobile? Or worse, your carrier is Sprint. Well if your situation is one of those you can give it a try to FreedomPop’s sleeve for iPhone 4 and iPhone 4S.

FredomPop’s sleeve gives you free internet on your iPhone. The sleeve case connects to a WiMax network and serves as a hotspot, so the iPhone will receive internet from the sleeve as WiFi. You can also use the internet from the sleeve on up to 8 devices, not just the iPhone. The sleeve is built-in battery charger to charge the iPhone for up to 6 hours.

FredomPop is currently taking pre-orders for this device for a price of $99. You will have free monthly data of up to 500MB. It is said that shipping for devices will begin this summer.
