Android Central forum member beezy has whipped up an Ice Cream Sandwich treat for you folks on Sprint with a Nexus S 4G. The Android 4.0.3 OTA for T-mobile’s Nexus S has been ported to Sprint’s Nexus 4G. You won’t see any wimax (4G), but 3G data, camera, WiFi, and bluetooth are confirmed working. You’ll need to be rooted and you can flash this ROM via Clockwork. You will also need to head over to the AC forums and be registered to download the file and you can do so from the source link below. Happy flashing, but do so at your own risk.
