>Google 4a user here. They pushed an update while I was on a ski trip in Korea - I updated an hour before getting on my bus and.. the application launcher started crashing on unlock. I couldn't open any apps.

I had that happen like a year ago while I was getting ready to go to a concert in another state. Luckily I was able to call my wife have her login to my gmail and forward my digital tickets to someone else in my party.
