I have just tested the omar911's "ICS 4.0.3 IML74K Build alpha 3c". It's close to stable version. The known bugs like camera, GSM, GPS, SD card mounted on PC, all works well on my phone, I don't know why.
But still met some faults:
1. Stops on importing multiple contacts (>100) -- all imported, but dozens of notifications stopped in the notification bar.
2. DSPManager stops when the headset plugging in. The headset works perfect in videos and adeos.
3. Maybe because of the headset, the Radio doesn't work.
4. System crash when loading Gameloft's "9mm".
These guys did really awesome work.
Expecting the next version!
