I wouldn't think so. It seems to be an HDPI rom. I don't know if I would like it on the Aria tho. I've messed with it a bit on the N1 and my buddy ditched it for CM, its a major battery and resource hog.
Thanks for the reply, it does look like a battery hog, but I hope that they keep making ROMs for the Aria. I had no idea what a solid little phone this thing is.
I haven't had a contract in years. Personally, I prefer to stay off-contract, as I can't afford AT&T rate plans. If I want a new phone, I buy it outright.
