I don't know of any other ports. Just this and the original for the N1.
Yea, I've had my eye on the original for a while, been hoping for a port. I'd switch back to Sapphire, but I've been on the CM 6 Nightlies the past 3 days, and they are stunning. They really don't deserve to be called nightlies, they're so stable. Watching the ROM develop has been a really interesting process, and really, they're just about up to CM standards.
I really like Sapphire, but Cyanogen will always hold a special place in my heart, haha I'm so sappy. CM 5.0.4.2 was my first ROM, and I've loved his work ever since. (Though I have had my affairs with BuglessBeast, ZeusDroid, DarkEdge, Kangerade, Sapphire, and Pl3x, haha)
