It’s only been days since we saw the latest Ice Cream Sandwich update make its way to GSM Nexus S. More recently, the official update for Nexus S 4G was leaked online. It’s not clear whether or not it’s a final release but everything does work on it. The official update for NS4G is yet to be announced by Sprint but we do know it’s bound to arrive soon via OTA. For the meantime, you can install IMM76D to ease your ICS woes. The update will wipe your data so remember to do a backup prior to installation.
Prerequisites
• Your phone should run on Android 4.0.3 Ice Cream Sandwich to be able to update it
• Fully charged Nexus S 4G or at least 60% battery capacity
• USB cable to connect the phone to your PC

If you are willing to wait, the official Ice Cream Sandwich update for Nexus S 4G will be available OTA via Sprint soon – we just don’t know when. It is based on Android 4.0.4, the latest version of Ice Cream Sandwich which brings hundreds of changes. With NS4G, the update reportedly improves WiMAX reception. Google has a habit of releasing updates to their Nexus line ahead of everyone else, which explains why Nexus S and Nexus S 4G were among the first to get it.
