I'm surprised that no one else has posted this here yet, but just in case you weren't aware, there's a great ROM from the
www.sholes.info site that came out yesterday. It includes:
-Wifi tethering
-2.1 Gallery, Music, Clock, Launcher
-Speed optimizations
-Multi-touch browser from the Motorola Milestone
-Other cool stuff
If you've tried previous versions of this ROM you'll notice that they've fixed the screen brightness issue on this version. I haven't been able to find any bugs with this ROM so far (except with the 2.1 Launcher, but I don't use it anymore since they added 5 screens to the standard home page).
I know 2.1 is going to be coming out pretty soon, but in the meantime I would strongly recommend you give this ROM a try. Check it out here:
