The LG Optimus 2X, Optimus Black, Optimus 3D and the Optimus LTE would be the first LG devices that would get the Android 4.0 Ice Cream Sandwich update confirms LG on their Facebook page. LG has just started rolling out Android 2.3 (Gingerbread) update for their Optimus 3D that brings lots of new camera features and for the Optimus 2x. They already confirmed the Gingerbread update for these devices last month for Europe on their Facebook page.
The LG Optimus black still runs on the single core 1Ghz OMAP 3630 Processor but has better performance than other single core Android devices. They would add more devices to this list in December that would receive the Android 4.0 update based on the features, functionality and the performance of the device. There is no time frame when these devices would receive the update.
