This is exactly the same issue I am having. This is posted on XDA. Originally Posted by Game4set So what are non-rooted users supposed to do?

We have a big Verizon flagship type store here (Mission Valley, San Diego).. I went in because I just wanted to see if the other phones were having the same problem. I tested out two thunderbolts, a Charge, and a LG Revolution. All of them had problems getting to
www.google.com. Also google searches take forever and the market was iffy. Basically it takes about 30 seconds to get a response from google. I pointed it out to one of the reps there and he was very thankful. He said he has been getting a lot of complaints about 4G phones being "laggy" .. When he tests them, they're fine. That's because he was going to non-Google sites though. When I showed him that all his display models were jacked up, he said he was going to call Verizon and open a ticket or something.
