Here's a thought, maybe because they aren't paid to?
I gotta say, the android community clashing with the traditional linux OSS community is an interesting thing to watch. In the linux world you wouldn't see so much sense of entitlement as you see with android devices. I guess that's because with a linux install, the community is still more full of tech minded people than it is of novices. With android, it's been thrust into the hands of the unsuspecting consumers.
The sad fact is that this is a being treated like a middle-of-the-road phone. Devs do like their sexy and sadly this device isn't as sexy as a SGS2 or the upcoming SGS3. Therefore interest is low. With the multitude of phones growing at such a rapid pace, there isn't enough talent out there to cover them all. If you want rom development, you gotta go for the phones the developers will want. And you also shouldn't buy something that has just come out.
From a tech side, even though this seems to have the specs of an SGS2, it seems internally to be wildly different from an SGS2. It is named in the SGS family and it'd not similar to anything there either. It's all ext4 (fairly different).
I've been working on this phone in my spare time trying to get a build that would run. I am not a programmer but thought that my skills were enough to hobble together a working CM7 device profile. I thought I could look at similar devices and come up with a working hybrid of other devices. Here's the thing.... there don't really seem to be any (or many) other msm8660 in the official repos. It's hard to find other devices that are similar to this one.
With ICS coming out for this phone at some point, I'm not even sure I want to spend that much time focusing on CM7 anymore since presumably we'll be able to get native drivers for the cameras at that point.
If you want to help, then offer to take up a collection to commission a dev's time or send someone a phone. It's difficult to do this process from a distance. I spent money on my own hardware and I'm deathly afraid of damaging my flash memory with constant flashes and what not.
