Google previously released the Android 4.0 update for the Nexus Slast year in December but the Nexus S 4Gfor Sprint was left out. A couple of months ago an Android 4.0.4 ROM leaked for the device, which made people hope that the official OTA update would arrive soon but that did not happen.
And now, we have another leaked ROM for the Nexus S 4G. This will update your phone to Android 4.0.4, bringing all the features that other Nexus S users have been enjoying for months, it has also got some improvements to the WiMAX reception, due to the updated base band.
Google recently started giving the Android 4.0.4 update to the GSM versions of the Galaxy Nexus and the Nexus S but not all have received this update, in fact few have actually received the update so far, with most choosing to simply flash it manually.
