I'm getting the best battery life of any of the ICS builds so far. Went to bed last night at 98% charge and 7.5 hours later when I woke up I was at 90%. Not as good as GB, but pretty decent. Everything is working great here. Installed the inverted apps with no issues after a full wipe.
My camera was buzzing so I extracted the camera apk from another Rom and copied it into system/app and overwrote the one that came with this Rom.
This is Tiffany84's status bar and dialer mod for FC15. I flashed it to test and now have the blue themed dialer as well as the blue status bar icons. Can't find anything that it broke. Running fine. Backup before you try it just in case.
Edit: tested my MMS. The inverted version disappeared from my app drawer after flashing this but the stock one and Hancent still work.
