Last week, JBQ from Google released full flashable images of the newly baked Android 4.0.4 (IMM76D) for a few devices - the GSM Galaxy Nexus i9250 yakju and the Nexus S i9020T (soju). The Nexus S release specifically wasn't compatible with the AT&T version (i9020A sojua), but an image for i9020A was promised at a later date. Additionally, builds for the Nexus S 4G on Sprint and other variants as well as the Verizion Galaxy Nexus were to follow.
Motorola Atrix 2 owners on AT&T are receiving an OTA update to v55.13.25, by AT&T reckoning. In Android versions, that would be 2.3.6, so sorry - no Ice Cream Sandwich for you, yet. Before your hopes are completely dashed, though, here are the full release notes:
If you've downloaded or had the Android 2.3.6 update pushed to your AT&T, T-Mobile, or unlocked Nexus S recently without issue, consider yourself lucky. None of this applies to the Nexus S 4G on the Sprint network.
While we reported that the update was breaking Wi-Fi and USB tethering initially, it seems something much, much worse is happening to some users who have received 2.3.6 OTA.
If you check out this Google thread, you'll see a number of poor souls have had all cellular connectivity stripped from their devices after updating.
Update: It looks like in order to fix one thing, you have to break something else. Reports are pouring in that this update breaks Wi-Fi and USB-tethering. Stay tuned for more details.
Owners of the Nexus S have been plagued by a notorious bug that activates Voice Search at random times, causing some serious interference when trying to accomplish even the most simple of tasks. Fortunately, El Goog has stepped up to the plate and addressed the issue, as an OTA update is currently rolling out that will put a stop to this annoying quirk.
