I was presented with the update the morning of September 1st and ever since then my phone has been garbage. What was normally a quick, responsive phone turned into a laggy POS. It is so slow I am tempted to go to Verizon and see what they can do.
As others said, I also lost 3G randomly today.
While i'm ranting, I might as well throw in that I don't like the new keyboard set up.
