Jump to the Top
Chances are that you've found yourself at the bottom of a very long web page, thinking that the only way to get back the address bar is to scroll, scroll, scroll your way to the top. Not so! Quickly jump to the top of any page simply by tapping the time.
Clear the History
Safari for the iPhone—like its desktop counterpart—will keep track of the most recent sites you've visited. However, if you're concerned about privacy, you may want to clear out the history regularly. Tap the bookmarks icon at the bottom of the page and, if necessary, return to the topmost level. At the very top you'll see the History. Tap it once to enter the folder, and then, in the bottom left, tap Clear.
Google or Yahoo? 
Safari's standard search engine is Google, but if you prefer, you can change it to Yahoo. Close Safari, and tap Settings. Select Safari, and then tap Search Engine. To make the switch, simply tap Yahoo. The next time you use Safari, tapping the magnifying glass will let you start a Yahoo search.
Managing Bookmarks 
It's essential to sort your bookmarks into folders; otherwise, you'll find yourself endlessly scrolling through a long list of links each time you look for a bookmark. Within Safari, tap the bookmarks icon at the bottom of the page. Now hit Edit, and then tap New Folder. Give the folder an appropriate name, such as “News Websites,” and then tap Bookmarks to choose a location for the folder. You can create as many folders as you want, and don't be afraid to nest folders in other folders.
Once you've added all your folders, you can begin sorting your bookmarks. Tap Edit (if necessary) and then tap a bookmark. A detail page with two distinct sections will slide into view. The first section lets you rename the bookmark, allowing you to edit long page names on certain websites. The second section lets you file the bookmark into one of the folders you've created—simply tap Bookmarks, and choose an appropriate folder.
Foil Auto-Rotate for Horizontal Reading
We’ll admit to curling up with an iPhone to read Safari in bed, but the screen rotation doesn’t match our view when lying sideways. (Try it now if you don’t believe us.) To keep the auto-rotating screen from twisting too much, orient the Home button up. The screen will stop twisting, leaving the widescreen view readable.
