The Android Open-Source Project has announced that Android 4.0 Ice Cream Sandwich Source Code is now available, this happened sooner as we expected. In a Google Groups post, Google engineer Jean-Baptiste Queru says “this is actually the source code for version 4.0.1 of Android, which is the specific version that will ship on the Galaxy Nexus.” Mr. Queru also warned that “this is a large push,” so developers should expect that “it will take some time to complete”.

“If you sync before it’s done, you’ll get an incomplete copy that you won’t be able to use, so please wait for us to give the all-clear before you sync,” Queru wrote.

This release also includes “the full history of the Android Code,” signaling the first time Honeycomb source has seen daylight.

We won’t be going to in to all the nitty-gritties, as this is only important for developers, the extremely impatient can hit that coverage link below.
