A few days back we announced that ICS had made its way to the Thunderbolt in the form of Liquid Smooth! There is now a JMOD version of the latest Liquid build by developer [SP]JESTER! This is the first AOSP ICS ROM with for the Thunderbolt with working RIL/DATA! All apps and Themes have been updated, some things that were not necessary have been removed, adobe reader and adobe photo editor were added, Google Now and Google Maps have been updated, MMS is working, Torch is working, 1x/3g/4g data all working, updated and tweaked menu settings. This is a pretty solid build with a good amount of customization.
Now that Battery info screenshot must be of a phone that has been idle, but i believe the developer is trying to show you that the battery life is better than average in this build. The Camera works, but the video camera is still not working in this build. Netflix is not working, but a patch is in the works for future builds. Wireless Tether app won't work, but wifi tether in settings will work.
Check out this Rom here.
