FreedomPop – a startup backed by Skype co-founder Niklas Zennstrom, which had started taking pre-orders for a 4G-capable case for the iPhone back in March, has now announced plans to release a 4G capable case for the iPod touch.

The company has already started taking pre-orders for the new iPod case dubbed FreedomPop Sleeve for iPod touch, which is available for $99.

Here’s FreedomPop’s pitch:

Turn your iPod Touch into an iPhone with the FreedomPop Sleeve: 4G data for your iPod Touch, Wi-Fi hotspot for up to 8 other devices, stream video and music anywhere, and you can even use Apple’s FaceTime wherever you go! Check out this video to learn more about the Freedom Sleeve for iPod Touch.

Freedom Sleeve for iPod touch case is essentially a WiMax mobile hotspot. It will allow you to make and receive calls using VoIP services like Skype. It will also allow you to make free FaceTime calls.

For $99, you also get 500MB of data per month with an option to buy additional data for $10 per GB. There is no contract or commitment so you can cancel it anytime you want.

Not only will the case provide 4G data speeds, it will also act as a mobile hotspot to allow up to eight devices to connect wirelessly.

The company hopes to start shipping the iPod touch cases in two months.

It seems like an attractive option if you have WiMax coverage in your area (which is limited), otherwise you may want to wait for the updated model, which will be compatible with Sprint’s new LTE network.
