I wouldn't return the phone just yet. This happened to me the other day as I was trying to pull up movie times form Harkins. The net woulnd't work at all. The area I was in was not a great cell spot but I had 1G. When I moved closer to home, the 3G signal came back....still no internet. Later, waiting for the movie to start, I decided to check...the internet ran like a champ. I don't believe in coincidence.....this many people with the same issue is either a "random" netwok problem or much needed update rather than a faulty phone.
Just my opinion.
