MrSeb writes with an article in Extreme Tech about progress toward getting an AOSP build working on the Nexus S. From the article: "Over the past week, ROM Manager extraordinaire Koush has been frantically working on making a working build of CyanogenMod 9 (Ice Cream Sandwich) for the Samsung Nexus S. The custom ROM, which is built purely from the Android Open Source Project, has now reached 'alpha 11.' All major features are present and no significant bugs remain. It's too early to say that the build is ready for prime time or mission-critical work — the final release of CM9 is due in the new year — but it's certainly stable enough for daily use. The most significant feature, if you can call it that, is that Koush's build of ICS is really very smooth — it's as nimble as Gingerbread, if not more so. Unlike the previous, non-CM build that was released last week, this alpha build of CM9 has every feature enabled, including Google Wallet, and setting a mobile data limit. As usual, the custom ROM is pre-rooted, has ROM Manager installed, and absolutely no bloatware. "
