Putting my two cents in, because I drank alot of coffee and I feel like it. HA
If you are going to go back to froyo, THIS is the rom to use. once you have everything the way you like it, make a backup so you have a froyo back up.
a couple of things....
1. If you want to use the theme chooser, kernel chooser, ect. make sure you are on CWM recovery 2.5.0.1 BECAUSE, if you are using a different recovery, or using a more up to date CWM it will not work. Wasnt made for anything else.
2. if you are having graphic issues with like the call log or contacts when your scrolling or things are over laping, remove the backround image. this will fix that problem.
3. if your galaxy s power widget is not staying on after a reboot, go in and change the indicator color. then it will. maybe a nice blue to match everything.
4. if you have trouble with CWM 2.5.0.1, like me, use the most up to date CWM and flash themes and kernels manually.
5. dont use TB to restore data. that app is good for one thing, and thats removing system apps.
6. THAT IS ALL
