Motorola officially announced that their Droid Bionic would see an upgrade to Android 4.0 in the coming months, however some users may get the taste of Ice Cream Sandwich on their devices right now.
Alpha release of a custom CyanogenMod9 port named Ics4Bionic has found its way to Droid masses at the Droid Forums. Features of this ICS port include:
Graphics working smooth now
ADB is working so we can track the rest
Both SD Cards
Phone and SMS works
GPS fully functional
Audio fully working
1x data now working
NOTE: you may have to dial *#*#4636#*#* (or use Phone Info from the market) and toggle data mode between modes. For me toggling to GSM or WCDMA and then back to CDMA only usually does it. Once you see the status change to unknown leave it there it takes up to a minute to connect.
3G/4G data….still sorting it out
USB support is still in progress sometimes it will mount in windows
Usual caveats and disclaimers apply to all brave souls that may want to switch to ICS ahead of the crowd — even without working 3G or 4G data, and with non-working camera. Then, the procedure is rather convoluted and based on use of a special SafeStrap bootstrapping utility for the Bionic.
