With the recent Cyanogen Nightlies on the Droid 2 (flashed nightly via Rom Manager Premium) I've been experiencing issues with 10% increments in the battery vs. 1% ones despite resetting the battery cache.
I've also been experiencing invalid signature issues with Nightlies 8 onwards downloaded via Rom Manager -- however I'm going to try getting them direct from here until I hear back from those developers since I'm not sure if it's a CM issue.
Also with Launcher Pro, I've been getting quite a few force close errors when booting up. On a more positive note, where Skype kept crashing on boot in the stock rom, CM has been handling that flawlessly.
Overall however, I love the rom and I'm glad to have it finally on my Droid after months of waiting! dancedroid
