In a gesture of good faith, Sony, on its developer blog, has announced the company is releasing the software binaries for the Xperia S. It has done so explicitly in support of Android developer JBQ's "experimental" support for the device in AOSP (found here). If you're unfamiliar with the project, we covered it earlier this month when it was announced.

The software binaries Sony released consist mainly of drivers for the hardware on the Xperia S's chipset. These binaries allow developers to get that hardware to function with non-OEM software. Manufacturers are generally under no obligation to make these binaries public, because they typically fall under the "proprietary" umbrella.
