Sony promised that most of their 2011 Android devices would be getting the Android 4.0 Ice Cream Sandwich update this year and it seems they are making good on this promise. The two devices that are now getting the update to Android 4.0 Ice Cream Sandwich are the Sony Xperia Arc and Sony’s Xperia Neo. Both devices will still be on Kernel version 2.6.32. These will likely be the last devices to get the upgrade from Sony with any new device coming with it out of the box.
The update brings many UI improvements and all of the features that we have grown to love in Android 4.0. Sony will be updating these devices as needed from ICS to newer builds of the same OS for bug fixes and such.
