6660 - What to put on it?

I am hopefully getting a 6600 2moro, and I was just wondering what peoples views are about the phone, but most importantly what are the cool apps that can be used with the 6600 alone. I own a 3650 atm, so I know of most of the games and stuff like that, but its stuff like the theme editor that I am interested in most.

Thanks in advance.
