I looked back at previous posts attempting to answer this question myself but couldn't. I see posts from the middle of June referring to a 4.3 update and since I'm already running 4.3 I'm can't ascertain what this update is. I checked for AT&T updates today and there is one but before I download it I'd like to know what it is. I use PdaNet+ for laptop tethering and I want to be certain it will still work after the update. Thanks in advance for answering my question.
