Didn't see any threads about theme's being install over pete's great BB Froyo Rom but I was able to get the Blue Energy Theme for Froyo install over it with no problems. I hate the white notification bar so this was just what I was looking for.
Also saw a few people having problems OC'ing BB Froyo so just wanted to let people know what worked for me.
Blue Energy Theme for Froyo here:
I was able to use the 1000 = 250/500/600/700/800/900/1000 with zero problems. A few others that I tried at higher speeds forced boot loops. 1000 is fast enough for me right now.
Hope this helps out some.
