Sit and wait. Its funny I've had 4 android phones and always read the forums for advice and stuff I may have missed but this is the most common post I see. There should be something on the box that says "your phone will tell you when it will upgrade"
SeriousLy, don't listen to the rumors just wait until one morning when your phone lets you know good things are here. You will drive your self crazy playing the ota update date game
