This story comes to us today by way of Rootzwiki. Rootzwiki developer dhacker29 has posted an alpha preview version of an Android 4.0 Ice Cream Sandwich ROM for the Motorola Droid Bionic.
This is just an alpha build but seems to be coming along pretty well. Dhacker29 reports that the graphics work smooth. Adb is working. The touchscreen, capacitive touch buttons, charging indicator, Bluetooth, SDcard external, gallery, bulletin screen shot and reboot menu all also seem to be in order.
They are currently working on wifi and phone data and getting the SDCard internal to mount.
The developer warns that this is still an alpha build and proceed at your own risk. He also thanks the other devs that contributed here.
