With a completely new version of Android comes a brand new build of LG's user interface. Aaron goes up close and personal with LG's Android 4.0 user interface at Mobile World Congress, and despite sharing some icons with the previous build, it offers some substantial differences thanks to the different look and feel of Ice Cream Sandwich. It'll be debuting on several of LG's mid to high-end smartphones this year, including the LG Optimus 4X HD.
