I decided to give this ICS ROM a try for fun today...after someone mentioned to me that the Captivate and Aria (as old devices) both have ICS.
It seems like it should work fine...for the most part...as an everyday device. As long as you can deal with having no working camera or GPS.
I didn't actually slip my sim card in...since it's not currently my main phone.
