Just thought I would share my experience so far. I decided to give a different Rom flavor a go, and went from a cooked DCD 3.2.3 to this. I loaded using the SD card method and it went very smooth.
Note: Make sure to follow the directions, especially the pulling of the battery and hard reset.
I normally cook my own roms, so loading a pre-built one was a bit exciting as I was not sure what I would get. The rom is very fast, and with all my bloated "Must Have" apps I am floating around 12-17MB free.
The Keylock app takes some getting use to, and even though it says you can use the hardware switch it does not work. I have not spent much time on it so far so it may be a simple configuration change.
All the utilities and applets are great. The little touches are very nice.
My only complaint is that I can no longer multi-select emails to delete them. It is probably just a setting somewhere but I have not had time to hunt it down.
Great job
