iPhone Life - Best Apps, Top Tips, Great Gear

When you do a search in Safari, it preloads the top search result in the background so that if you do indeed select that result, the page will appear almost instantly. What this means, though, is that if that's not the web page you want, you've already used up some of your data to preload it. This is fine if you're on Wi-Fi or an unlimited data plan, but perhaps not a good idea if you're trying to keep down your data usage. Fortunately, you can turn off this feature, thereby avoiding data usage for web pages that you may not want to access.
