The Nexus S showcased the first Ice Cream Sandwich leak, on an Android phone, last year. Subsequently, there have been numerous leaks, official updates for other GEDs like the Xoom, as well as a variety of non-GED devices; but what we have here is a leak for the ICS out-of-the-box experience with the Galaxy Nexus (the successor of the Nexus S).
XDA member mrxkills has posted a leaked, official firmware update, for the Nexus S 4G or the CDMA variant of this fantastic device, that has made it’s way to the developer community over at XDA. It’s interesting to note that this update is based on Android ICS 4.0.4, which is one-up over the 4.0.3 leaks that we’ve been seeing all this while. But then, this is a Nexus device, and hence, likely to get the latest and the greatest, as far as official updates from Google are concerned! Those of you who are lucky enough to own one of these babies, can download this firmware and enjoy the official creaminess of Ice Cream Sandwich on your Nexus S 4G, by updating it manually.
This update brings a new software modem, bootloader, and a new build number — IMM26 — Android version 4.0.4. Most of the features are working, including the WiMAX radio (this should bring up some smiles)
