Hi all, I have a 32GB black iPhone 5 running 6.0.2. Browsing on either 3G or LTE is fine with no lag whatsoever. Using wi-fi is another story. On three different wireless networks (each with a different speed, service and router), Safari will sometimes work fine and other times lag tremendously to the point where I would need to stop and refresh the page for it to load. Has anyone else had this issue? This happens even when the phone shows a full wi-fi signal.
