I installed this OS and unlocked the themes. After using it for the past couple of weeks, I have some subjective impressions.

I've had one instance of the unit freezing, but it doesn't seem to be any worse than the previous software.

It seems that the battery life is somewhat reduced, but it's hard to be sure.

The multi-tap problem seems to be gone but the phone is still completely braindead when it comes to entering numbers like 1-800-GOFEDEX. Why can't they figure this out?

Other than that, I haven't encountered any problems. The phone seems to work fine.
