What I've noticed so far:
- The signal indicator is indeed broken, and will only show a single bar. Network performance seems fine, so no biggie.
- Long-pressing the home button won't do anything, so you'll need to use pie controls for app switching. It would be great to be able to map the buttons, or at least have the long-press gesture available.
- External SDcard isn't available.
The ROM itself is performing very well, and if the above issues aren't important to you I'd certainly recommend using it. Bluetooth A2DP is working just fine, although it did fail to connect the first time I tried. All was fine after a reboot.
