Remember a few months back when Sony shocked everyone by releasing an alpha build of Ice Cream Sandwich for some of their devices? Well their developers have been hard at work and have decided to show everyone how they are doing as of late. They have another build of ICS up for a few devices, but they do not want everyone to install it.

First things firs, this build is for the Xperia Arc S, neo V and ray. Everything seems to be pretty snappy in this build, but the developers have taken a few things away from the build to keep everyone from installing. The radio is turned on for calls and internet but WiFi and Bluetooth are absent. The biggest hit however is that all Google Apps are pulled from this build.

To install this you will have to have your bootloader unlocked through Sony’s website here and will have to be updated to the latest Xperia firmware which is 4.0.2.A.0.42. Once you have that done Sony provides good instructions for installing the build, there is one interesting note however:

Also, if you unlock the boot loader, you will not be able to download and install the final Ice Cream Sandwich software upgrade for Xperia™ phones.

So to test the build you have to unlock your phone but to get the final update you are going to have to re-lock it? Seems a bit redundant on Sony’s part but I guess that is the price you pay to have early access to this Android 4.0. Head on over to Sony’s site to get started.
