Apple iPhone 3G S

Try looking trgouhh your phone’s menu to explore the GPS feature. Unless it comes with a built-in map, you will most likely have to download the map from somewhere on the internet.I looked up this phone’s specs and i see it comes with A-GPS support, which is a great feature that uses network resources to locate and utilize satellites faster and better in poor signal conditions, where traditional GPS may fail. Here’s how to turn it on:1. From the Home screen, find and tap Settings.2. Tap Security and Location. 3. Mark the Use GPS checkbox. Tap Agree if you consent, and that’s it, you’re all set.
