We're extremely happy for Nitro HD users, because ICS is a critical update. It practically reworks the whole platform, making it faster and much more stable. It also brings a brand new user interface, of which customers will see very little, because the stock ICS UI will be customized by LG's Optimus 3.0 UI. The main changes made by Optimus 3.0 include new lock-screen options, different icon-set and other graphical element changes, Downloads tab in the main menu and a few others. All in all, there's nothing too fancy about Optimus 3.0, but the good news is that all the great functionality found with ICS will be present, including better multitasking, new keyboard, Face Unlock and many other.
What a great end of the month for LG Nitro HD users, eh? Be patient, guys, only a few days left until your handsets regain their cool-factor!
The update should be available OTA, but strangely, AT&T doesn't mention this option. Instead, it says that customers should visit the following link to get the update: Nitro-HD-ICS-Update.
