In HTC parlance, the "Neon" codename denotes a device of the Touch Dual form factor -- original Touch styling plus a slider keypad, a drill we all know by now. This particular form factor seems to be a pretty popular one, too, considering the sheer number of variants HTC's turned out; at this point, we have one for Europe, one for North America, and one for Japan, and a new FCC filing suggests that there's still at least one more trick in that pony. The so-called NEON400 doesn't give much away from the ID label document that we see here, but test reports indicate that it's sporting CDMA 850 / 1900 -- just right for launching on Sprint, Verizon, Alltel -- you get the idea -- and obviously, we'll see EV-DO in there as well. Against the Touch Diamond, the Dual is starting to look just a little dated, but it gets that all-important keypad that the Diamond lacks -- so even networks that end up launching the Diamond can realistically make room for this one in the lineup when it's announced. By someone other than the FCC, that is.

Why wait for the Dream when you can get Android all up in your HTC piece today? Numerous efforts over on xda-developers have yielded a high success rate in getting Google's still-young platform working (although the definition of "working" can vary from device to device) on a variety of recent and popular HTC models, so if you dig your hardware but you're ready to give Windows Mobile the boot -- and you like to live on the bleeding edge between functionality and brickage -- give it a shot. Drop us a line if you have a port to add to the list!

Okay, so we know of at least two HTC devices codenamed "Neon" that the friendly bureaucrats up in the FCC have been forced to go through with a fine-tooth comb. Now we have a third -- the descriptively-named NEON300 -- and this might be the money version. As we've pointed out before, the Neon series appears to represent a line of Touches with different guts for different carriers and locales, and the NEON300 possesses something that's music to the ears of the yanks in the audience: HSDPA on the 850 and 1900MHz bands. Along with the recently-announced US Touch Dual, this should be quite a gem in, say, AT&T's lineup -- and with Sprint and Verizon both rocking the same device, can they really afford to turn the other cheek?

Update: Pictures of the unit being poked and prodded can be found deep within the test documentation, and sadly, it turns out this is nothing more than the US Touch Dual after all. But come on HTC, seriously, you know you want to make a straight-up Touch with North American HSDPA, too. Thanks, uofmrapper1!

Remember that NEON100 we spied via the FCC's loose lips a few weeks back? Turns out there's at least one more version of the Touch variant being prepped -- but this time, the info comes from another famously leaky source, the Bluetooth SIG. Details are extraordinarily slim here since we don't even have the benefit of an RF test report, but we do know that it'll support Bluetooth 2.0 + EDR (seeing how this is the Bluetooth SIG's database and all). In a perfect world, this sucker would turn out to be a Touch with triband HSDPA, but odds are, we really won't know until HTC is good'n ready for us to know.

So we're not too sure what's going on with this here "NEON100" from HTC that just found its way through the FCC's bureaucratic labyrinth. Is it yet another Touch variant? Yeah, it clearly is -- just take a good hard look at that label sample. It's also recently passed through Japan's certification process, and we're seeing some talk across the 'nets that it could be destined for NTT DoCoMo, but we don't think it's the HT1100 since we're not seeing any hint of a slide here. Even more confusing, the test reports are referencing WCDMA Band V -- North America's version of WCDMA on the 850MHz band, versus Japan's Band VI. Ah, screw it, the point is that we're pretty sure this isn't destined for the States unless it's tucked neatly away in the briefcase of a Japanese traveler. Shame, too, since we sure could use a Touch with HSDPA 'round here.
