I`m not a dev but I make a port from Maclaw rom (cm_gio-ota-eng.maclaw.beta1) and its works almost 100%
Use CM7 to port from "samsung gio" rom.
Just change de camera.apk with a ISC camera to work, gallery2.apk to cm7 gallery.apk.
Fisrt time reboot gummybear stop working but just need to put a wallpaper to work or reboot
Windows dont recognize the driver but can charge the battery ops:
I dont know more bugs............. :?
ALL CREDITS are for MACLAW
