SamMobile. The cheeky guys there say that the newest build, dated January 29th, is ready for regular daily use after a collection of improvements. The build number for the latest leak is I9100XXLPB.
ClockworkMod Recovery Touch, a new version of Koushik Dutta's ubiquitous custom recovery software. Initially offered earlier this week, the touchscreen enabled pre-boot environment is now available on more Samsung, HTC and Motorola devices. Initially developed for only the Galaxy Nexus and Nexus S. But a recovery system takes a lot less time to modify than a full ROM, so we're seeing the updated software spread out quickly.
Google+ account, but did not offer a download.
RootzWiki (currently experiencing uptime issues), though at this point it's far from finished. While the basics are in place, including Android 4.0's much-improved tablet interface, a host of early bugs will discourage all but the most dedicated of modders.
SamMobile are at it again, releasing newly uncovered versions of the official Ice Cream Sandwich update for the international version of the Galaxy S II. Two new versions are available, running Android 4.0.1 and 4.0.3, with the labels I9100XXKP4 and I9100XKP8. It's not clear why you'd choose the earlier ROM, but they probably chose to include it for the sake of completeness. These are the official Samsung software updates in alpha/beta form, complete with the TouchWiz interface - for better or worse.
CyanogenMod 9, the Ice Cream Sandwich release, with the customized Trebuchet launcher app. But that's certainly not the only thing Steve Kondik and his army of coders is cooking up. The new ROM will have a brand-new Music player app, with a considerable amount of extra functionality.
MIUI ROM for Google's favorite son. Different builds for the GSM and CDMA Galaxy Nexus are available over at XDA, both compiled from the official MIUI source code from popular ROM developer DroidVicious.
XDA have zipped up the latest radio firmware for your phone and posted it in a flash-friendly format. The software itself comes from the latest OTA update, but the radios themselves can be used on any ROM.
