One of the most popular Android devices from 2011 was, without question, the Samsung Galaxy S2. Starting today this phone will receive nightly builds of the new generation CyanogenMOD - version 9! There's no need to say that it's Ice Cream Sandwich? :P
@Codeworkx informed us this morning that the Galaxy S 2 specific sourcecode was now merged into CyanogenMod mainline which will open up the repo's for all and give us the daily dose (the nightlies) for our ORD (Obsessive ROM updating Disorder).
The nightlies can be downloaded from ROM Manager (one my most used apps) or directly from the CyanogenMod site. A nicely done device specific changelog, which listes all commits merged affecting the SGS2, can be found on the CM nightlies site. Because @Cyanogen was asked by Google to remove the Google proprietary applications from their CM build a while back, these must be flashed separately.
For those of you eager to compile your own version of CM9, head over to cyanogenmod's wiki. The guide is pretty easy to follow, but you'll have to change "gingerbread" to "ics" in the instructions. If you get stuck, you can always post here and i'll help if I can!
