Ice Cream Sandwich will be made open-source, after Galaxy Nexus release

An Android engineer, Dan Morrill aka morrildl, told the good folks on in the Android Building Google Group that the source code for Ice Cream Sandwich will be put into the AOSP repositories, but not until after it has been made available on devices. Given that we haven't been given an exact date for the release of the Samsung Galaxy Nexus, that means we also don't have a real window for the release of the source code. 

It seems fairly safe to assume the ICS code will be made open source next month. So, if we're really lucky, we'll be seeing Cyangogen 9 start hitting devices early 2012 sometime.
