Sporting a HSPA+ Samsung GALAXY Nexus (i9250) or an UMTS/GSM Nexus S (i9020), well, you might want to check System Update for a brand new update that Google took to Google+ to announce: Android 4.0.4.
Android 4.0.4 is also rolling out to the Motorola Xoom Wi-Fi, which is a bonus. At the moment, the Android 4.0.4 update isn't going to arrive on the CDMA-based versions of the phones, not yet anyway. What about Verizon GALAXY Nexus' phones, or Sprint's Nexus S 4G? No word on that yet either.
If you've gone one of the above phones, we suggest you update. Ice Cream Sandwich is beautiful and if you have a smart device capable of being updated to it, you should do it.
