I was working on the gingerbread (2.3.7) harock posted. I managed to make it work with 22.214.171.124 kernel (its original one was 2.6.32, but i couldn't build a working 2.6.32 kernel).
Currently it has many issues. Most problematic ones are:
-Wifi cause phone to freeze -> Even setting WiFi-sleep policy to newer doesn't completely resolve this issue
-GPS cause phone reboot -> a similar issue and a temporary workaround i haven't tested yet could be found at: http://forum.xda-dev...d.php?t=1373183
-Once GPS is used can't turn it off
-As usual Camera flash is not working
-Taking photos may sometimes cause Camera app to freeze, Video recording and preview works ok -> a similar issue could be found at http://forum.xda-dev...911828-p-2.html
I will try to resolve these issues if i have time.
Although it is completely experimental if you want to try the rom it is here http://www.mediafire...cmi98859lo94zy3
While some of the issues may be originating from rom system files (I can't do anything there: I don't have Android AOSP or CM AOSP and i can't download it either because i don't have enough hard drive space and i am on mobile connection only). Most of the issues above are probably related with kernel configuration if you want to give a hand here is the kernel source https://github.com/r...-kernel-msm7x27
I hope someday this rom works without issues.
