I don't know when Alpha will be coming, but I'm guessing it must be soon! e-yes has been working on NITDroid a lot recently, and he hasn't been tweeting about what he's done; he must be too busy to tweet all the changes he has made. But, he has made some more progress none the less :
You can now play audio through loudspeaker, headset and earpiece.
Also you can now have root access to ICS via adb shell; su/Superuser.apk.
Along side the updates he has made above, he has also been working on the 'back-end', so more things are compatible, but at the same time, more faults have occurred.
What is not working (Critical):
Reboot/halt (in R&D / regular mode) few minutes after entering suspend [realized; NOT FIXED]
I'm sure more things will keep coming. I'll stop posting here with small updates for a while now, since I maybe seen as 'spamming' the place with small updates. I'll only post once the big updates are made.
Tried a few hours ago and it works great. Easy to install and all things stated in status as working seem to work (hav'nt had time to test all features)
