UPDATE Jelly Bean Binaries:Available For Sprint Nexus S/4G, Xoom WiFi – GSM/Verizon Galaxy Nexus Updated (Sprint Galaxy Nexus Absent).GET NOW!!

Some good (and not so good) news for lovers of Android development and the wonderful custom ROMs that result from it. Google has officially posted the binaries for a handful of Nexus devices, including Motorola Xoom WiFi and both the Sprint Nexus S 4G and GSM variant. Binaries were also updated for the GSM Galaxy Nexus and Verizon Galaxy Nexus with, sadly, only Sprint’s Galaxy Nexus missing out on Jelly Bean AOSP goodness.

Googler Jean-Baptiste Queru revealed the good news today via the Android Building Google Group:
 A new set of proprietary binaries for Jelly Bean are available at
    https://developers.google.com/android/nexus/drivers
This adds binaries for crespo (Nexus S), crespo4g (Nexus S 4G) and    wingray (US WiFi Xoom).

    This also updates the binaries for maguro (GSM Galaxy Nexus) and toro
    (VZW Galaxy Nexus).

    All those binaries were tested against android-4.1.1_r3, i.e. JRO03H.

    Binaries for grouper (Nexus 7) are unchanged since JRO03C and are
    suitable for JRO03H.
