Team CyanogenMod is continue working on the development of CyanogenMod 9.0, and now our nice developer Nadlabak just released his new ICS custom rom for Milestone after two month, it is CyanogenMod 9.0 RC0 for Milestone A853, in this build, we get working camera and new CM9 boot animation, and many upstream improvements from team CyanogenMod. I’ve tested the Ice cream sandwich on Motorola Xoom, hopefully we can get full working CyanogenMod 9 on Milestone soon or later though I know it is a hard work with limited RAM.
Btw, Devs are also working on enabling zram function on Milestone, this new feature can help a lot in limited ram situation, more details can be found here: https://code.google.com/p/compcache/
