So, two days ago Google started rolling out some updated Ice Cream Sandwiches. Namely for the GSM Galaxy Nexus and the Nexus S. So where's the love for the LTE Galaxy Nexus?
Well, according to Google, the reason is that they no longer consider ANY CDMA devices to qualify as "developer phones". Now, lots of people read this as "Google no longer supports this device" but that is simply untrue. They are still developing and building the Roms for these devices, the difference is that they cannot push it directly to the phone, nor release it for users to install. The reason, according to Google, is that the technology behind CDMA devices (used by Sprint and VZW) require the carriers to "sign a key" that enables telephony functions. Because Google cannot DIRECTLY update these devices, they no longer consider them "supported developer devices". But rest assured, they should still receive timely updates like their GSM cousins. "Should" being the key word as we all have grown to distrust carriers, especially when it comes to timely updates. Nevertheless, its only been about 48 hours since the 4.0.4 Rom was released so I'm willing to be patient. If VZW hasn't pushed out the update by next Friday, I'll start steaming....if its not out by the following Friday I'll be leading the angry mob!
