This post is for everybody having issues with I.C.S. thanks to jeffdenver for posting a link in another post. I highly reccomend everybody head to
www.androidpolice.com. search for a post they did on Aug 15th that deals with the rezound getting another update, download and install that update. The build number is 4.03.605.2. It is the best build I have used so far. It has fixed all of my issues at this time. Read the instructions close, as it WILL wipe your phones data. You can install mybackup from the play store to do a complete backup before flashing the RUU so that you can restore your phone to the way it was before flashing. Also you MUST be completely stock.
