Engadget has gotten an exclusive tip from a “trusted” source revealing the codename and details of what could possibly be the first 4G Android device to hit the market.  Codenamed “Supersonic”, the device is made by HTC and will launch on Sprint with WiMAX capability.  Here are the official bullet points taken from Engadget:

• Codename is “Supersonic” — a name we’ve heard at least once before.
• Feels a lot like you’d expect an Android-powered HD2 to feel thanks to a 4.3-inch non-AMOLED display and a svelte shell. (For reference, the HD2 is 11mm thick, but we don’t have exact dimensions here.)
• It’s got a kickstand on the back. This wouldn’t be a first for HTC; the Imagio on Verizon has one, for example.
• Runs Android 2.1 with HTC’s Sense UI.
• Our tipster saw it in white; production devices could be available in different colors, of course, but white seems like it’d be an intriguing choice for a phone of the HD2′s size and shape.
• The phone’s software stack is buggy enough right now to suggest that we’re not looking at a release any time soon, but we don’t have details on the projected launch window.
• It’s fast – Snapdragon fast, it seems, though our tipster can’t confirm the processor under the hood.

As you can see from the below comparison taken directly from Sprint’s website, 4G is a significant upgrade from 3G in terms of download speeds.  There are also many other technicalities to the improvements and you can go here for those details if you desire.

Although 4G is not currently available nationwide, one can’t help but think that this may change quickly and if Sprint wants to get ahead of the competition they have all of the tools here to do it.  An HD2-like device, the latest iteration of Android with Sense UI and a 4G network ought to do the trick.
