My roommate and I just rooted my phhone and I'm looking for some good mods. I'm running cyanogen but I want more stuff haha
My favorite mod is Dark Edge UI,
[Release] DarkEdge UI 2.2
In the coming days it will also include a completely customized lockscreen with slide up to unlock and music controls(I know other roms support lockscreen music controls)
It can be a little tricky to put on if your new but you can easily get help in their IRC. I don't think there's anything out there that looks quite as good or affects the system UI as much as DE.
It worked very well on the ese81 build(android 2.1) Here's screenshot of DarkEdge in action including the lock screen(upper left screen shot):
This one below is newer but doesn't have the custom lockscreen as it hasn't been released for 2.2 yet.
