The new Samsung Galaxy Indulge (MetroPCS -- LTE) and the stellar Epic 4G (Sprint -- WiMax) go head to head in a intergalactic 4G speed test. The device that renders webpages while browsing over a 4G data connection wins. Please note: we tested each device in San Francisco, CA. We didn't clear the browser cookies from either device. Although we did see the 4G icon while testing the Epic, it's possible that the enabled Wi-Fi connection slowed down it's browser rendering speed.
