You probably know that your iPhone has a .com button for quick domain extension typing, but did you know you don't even have to use it? If you want to go to a .com website, all you need to do is type its name.
When you're in Safari's address bar, don't bother typing www. or .com. Just type what goes in the middle. For example, if you wanted to go to www.flickr.com, just type flickr and Safari will do the rest for you. This won't work for domains with other extensions, but since many of the sites you visit probably use .com this can save you quite a bit of typing.
